Frequently Asked Questions about LTM Energy's Solar PV Offering

    1. Do solar systems require approval by City Councils?
      Each council has its own policies. If your council requires approval, LTM Energy will compile all the necessary paperwork on your behalf. We will also handle any negotiation that is needed with your local electricity authority.
    2. Do you supply Solar Geysers for water heating?
      No. LTM Energy is a specialist solar electricity solution consultancy and advisory company and does not provide any water heating products per se.
    3. Is your PV solution competitively priced?
      LTM Energy has been involved in numerous solar projects across South Africa, in both the residential and commercial markets. This has stimulated an efficient project management capability. Our large scale of operations has increased our buying power and helped us develop strong relationships with our suppliers. We procure bulk discounts which are passed along to our customers.
    4. Do you lease solar systems?
      Yes: LTM Energy has a ‘lease to own’ option. The cost and the structure will be determined for each individual customer. However, we enable you to have a solar electricity system without having to commit to an initial capital cost.
    5. What are my purchasing options?
      Our commercial and business clients fit into three categories:
      • Those who want to buy their solar power system outright (own financing)
      • Those that want to buy / own the system but want no initial capital payout (lease to own)
      • Those who want to buy solar electricity without having to buy and/or maintain the solar system (LTM Energy financing / SPPA)
    6. How much does solar cost?
      Whilst the exact capital layout and/or cost of energy produced by a solar system can only be determined once the detail of the site and project is known, latest projects has proven that most gridtied PV systems with a capacity of 300kWp or more can be constructed at below R10k/kWp Alternatively, we can install your PV system with no upfront cost and you can pay less for clean, abundant solar energy than you pay for your grid-supplied electricity - at a price below R1.00/kWh in most cases.
    7. Is the cost of solar PV justifiable?
      The cost is relative to the value being generated. When LTM Energy designs a solution, the pay-back period is taken into consideration to ensure that it suits the customer’s needs and affordability. Electricity costs will be present for as long as your business is operational. The idea behind our solutions is for customers to obtain an asset without incurring any additional cost over and above the rising cost of electricity.
    8. How long does it take to pay back a solar electricity system?
      There is no set time period. It depends on the current electricity cost, how much of the daytime base load can be replaced by solar and the cost of the installation. Our feasibility study for each individual solution calculates the payback period. Recent projects have a proven payback period as low as 4 years.
    9. What is the difference between a Grid-Tied and Off-Grid solution?
      A Grid-Tied solution needs electricity from a utility provider grid or a generator to provide power for use during load shedding and power outages. An Off-Grid system is an electrical system that operates independently from the utility grid. The consumer is 100% self-sustaining and is not reliant on a utility provider. It generates and distributes its own power from solar PV. Off-Grid systems require a backup (either storage/batteries or a generator) as it provides PV power during a limited number of hours when the sun shines.
    10. Does an Off-Grid solution cost more than a Grid-Tied solution?
      Yes. The Off-Grid option makes use of storage, such as batteries, that add significantly to the initial cost as well as to the operating cost. The batteries need to be maintained and replaced much sooner than the life of the Solar PV system.
    11. Is it possible for the Grid-Tied solution to feed back into the grid?
      If a Grid-Tied solution produces more power than the load required, it could feed back into the grid. Most Utilities, however, do not allow this, in which, a case-specific “reverse power protection” is required. Certain municipalities, however, have granted permission for electricity to be fed back into their grid. LTM Energy is knowledgeable regarding and can assist in this application.
    12. What is an Inverter?
      A power Inverter is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). The design of the device or circuitry determines the input voltage, output voltage and frequency and overall power handling. In layman’s terms, the Invertor is responsible for converting the DC power generated by the PV panels, to AC power which is needed to run in parallel with your grid power and to operate most commercial and industrial equipment.
    13. Can Solar PV produce 3 phase power?
      Yes. However, it is dependent on the design of the systems. We employ qualified electrical engineers to design your system.
    14. What is Wp or kWp?
      Watt peak (Wp) or kilowatt peak (kWp) which is 1000 Wp, refers to the maximum power output of a Solar PV module. A 500Wp module would, therefore, produce 500 Watts of electrical power during an hour of peak / full production.
    15. Do solar electricity systems require maintenance?
      Solar systems are relatively low maintenance since there are minimal moving parts. Panels are designed to be self-cleaning when it rains, and in most areas, annual or six-monthly cleaning is sufficient (using a hose and soft brush). Inverter fans and air vents need to be maintained at similar intervals, depending on the environmental conditions. A tailor-made maintenance program is suggested for each installation.
    16. What warranties do you offer?
      All our systems are backed by manufacturer’s warranties and/or customer requirement. E.g. o Panels: Guaranteed to produce 80% output at 25 years. o Inverters: Guaranteed for 7 to 10 years. o Workmanship is guaranteed for 36 months (negotiable). o Mounting structures are normally guaranteed for 5 years (negotiable). o System Up-time guaranteed to be 98% (if we designed and built the system and a proper monitoring and maintenance contract is in place). o Performance guarantees can be negotiated.
    17. Will a Solar PV solution reduce my risk of power failures?
      An Off-Grid solution is designed with batteries that will supply electricity when the grid cannot deliver power, thereby reducing the risk of power failure. The quantity of power that will be available, is dependent upon the size of the PV and battery storage unit. A Grid-Tied solution does not reduce the risk of power failures per se, but rather the cost of power. LTM Energy suggests the use of a generator that has the capability of delivering the required / minimum amount of electrical load needed. Our technology enables the Grid-Tied option to integrate with the generator thereby reducing the operating cost of the generator.
    18. What is the fundamental difference between residential and commercial solutions?
      Commercial and industrial solutions focus mainly on money savings through reduced operational costs and are usually Grid-Tied with no battery back-up. Residential solutions focus on reducing risk and ensuring comfort in instances of loss or shortage of power. The electricity that is generated by direct sunlight needs to be stored for use in the evening and early morning and during inclement weather. Commercial and industrial systems enjoy additional tax benefits e.g. accelerated depreciation.
    19. How doe’s location and weather affect a solar solution?
      The LTM Energy team makes use of detailed data from the last 15 to 20 years to determine the amount of available sunshine to produce electricity. This is referred to as the PV yield, measured in kWh/kWp (kilowatt hour per kilowatt peak).
    20. Does the weight of solar panels affect my roof structure or roof warranties?
      Each panel typically weighs around 18kg, which is spread over 1.5m2. It is recommended that the roof structure have a weight bearing capacity of 20kg/m2. It is recommended that a qualified professional determine whether your roof structure is suitable for PV installation.
    21. How much of roof space is required?
      The design norm is 10m2/kWp, which allows for proper installation and maintenance. However, areas with shadows, orientation, etc. may result in a different number.
    22. How do I know whether I have a roof that can support solar panels?
      The roof needs to be in direct sun and in good shape structurally. In South Africa, a roof that faces a northerly direction yields the best results. Solar installations come with warranties for between 20 and 25 years. It is therefore advisable to attend to any renovations on a roof before the installation of solar PV panels takes place and to allow for maintenance of roof, in the design. Ensure that all foliage is pruned to prevent obstruction of the panels.
    23. What size system do I require?
      A solar feasibility assessment needs to be conducted to calculate the size of the system required. This assessment tests site suitability, a compilation of an energy audit and performance modelling. Higher power demands require bigger systems and vice-versa.
    24. What equipment can I power from the system?
      In general, any equipment that is powered by electricity can be powered by a Solar PV system. The system design varies according to the type of equipment that needs to be powered.
    25. Will a solar solution increase the value of my property?
      Yes. Through the supply of Solar power at a known cost, you are protected (partially if Grid-Tied from future increases in electricity prices. In many cases, Landlords are installing solar electricity systems as another revenue stream. This can be used as a marketing tool to justify higher rental rates and to increase a property’s occupancy rates. In many cases, rooftop PV has been found to have a substantial impact on cooling of buildings.
    26. What is the lifespan of Solar PV systems?
      Solar PV panels are designed to last for 20 to 25 years. Some systems are able to last for as long as 35 years. PV installations thus are designed to have a similar lifespan, but some components might need replacement during this period (like Inverters) and/or need to be well maintained.
    27. Are the solutions resistant to extreme weather conditions?
      Solar technologies available at present are subjected to stringent testing in all types of weather conditions to ensure durability and reliability. They are becoming more weather resistant than in the past.
    28. Can the number of solar panels I have, be increased in the future?
      PV systems are modular. More panels and Inverters can be added at a later stage as the need changes. LTM Energy ensures that a solution is “tailor-made” according to the customer’s requirements. Often infrastructure is incorporated in the initial installation to ensure that future growth of the system is possible.
    29. What is a Solar Power Purchase Agreement (PPA or SPPA)?
      A PPA is an agreement to purchase power at an agreed price and price path for a fixed period of time. With Solar PPA (SPPA) agreements, you don’t purchase the solar system, but you only purchase the power it produces.
    30. What are the various contracting options?
      Any form of PPA / SPPA can be negotiated, whilst the most common are:
      • Straight buy-out option: Full turnkey solution but client pays for the project
      • Leasing/roof rental: LTM rents the roof and offers the landlord or the client the same price as their current tariffs or slightly lower
      • Lease to Own: LTM fund the project and the client pay’s off the system over a predetermined period, over and above the purchase of electricity generated.
      • SPPA: Solar Power Purchase Agreement where LTM fund, install, own and operate the system whilst the client purchase all electricity generated, mostly at a rate below current utility rates.
    31. Does LTM Energy offer lead fees for referring opportunities?
      Yes. LTM Energy has an approved policy for incentivising successful leads, as long as there is no conflict of interest. Fees are based on deemed profits using a percentage of revenue or

       

      referenced on a percentage of total kWh sold.
    32. Can your company deliver given scalability?
      We have national installers and our company is strongly backed by an international partner with over 660 000 people globally. We have written several success stories to date including national rollouts with Government, Eskom and private blue-chip clients. LTM Energy has a scalable organisation structure that was designed specifically to accommodate high growth and/or scalability.

  1. Why do companies invest in Solar PV Projects?
    The most common drivers are as follows:
    • Strategic. In some cases, the primary driver is strategic e.g. where the board regards renewable energy as an integral part of the company’s business strategy. Strategic considerations include such issues as securing access to energy in the future and addressing shareholders’ expectations.
    • A subset of secondary strategic drivers, are to ensure the long-term security of energy supply, or whether the company has identified a strategic opportunity for the future capacity building.
    • Financial and Economic. In some cases, PV projects are implemented for financial or economic reasons and show positive returns on investment as measured against the company’s investment criteria. Returns may include financial incentives such as government subsidies, tax incentives or other forms of finance. The bank has to determine whether financial goals are immediate, longterm, strategic or a combination.
    • Marketing and Branding. Many companies are beginning to realise that there is an increasing demand for green products amongst consumers. The adoption of renewable energy is seen as a differentiator in the market, and competitive pressure may prompt the investment in renewable energy or form part of a larger brand-driven initiative.
    • Regulatory. The regulatory drivers are divided into command-and-control measures and marketbased mechanisms. Provision is also made to distinguish between current regulation and anticipated regulation.
    • Regulation that enforces a reduction in purchased grid electricity such as the Power Conservation Project planned by Eskom a couple of years ago, would be an example of a command-and-control regulation. A carbon tax, on the other hand, is an example of a market-based regulation. The latter is imminent and a reality. PV projects should be seen as a risk mitigation measure, as it uses clean energy that will lower the dependency on Eskom grid power that uses fossil fuels, hence a reduction in carbon footprint.
    • Sustainability: Companies are beginning to invest in communities and sustainable technologies either because they believe it is the right thing to do or because they have conducted comprehensive climate risk assessments and realise that adaptation measures are required. Companies are investing in renewable energy due to social investment or climate change adaptation agendas or both. Companies could choose from a range of sustainability drivers including:
      • Social and community benefit
      • Adaptation and/or long-term environmental benefits
      • Scientific Reasons
      • Enhanced impact of CSI spends
      • Environmental efficiency
  2. What are some of the funding criteria: Funding is approved on a case by case basis, but high-level funding criteria is
    • LTM and its strategic partner's finance projects in full, providing own mix of equity and debt financing. EPC (Engineering, Procurement & Construction) should be done by LTM Energy and/or our choice of subcontractors.
    • We are targeting projects from R3m to R 100m at an average of R10k/kWp, it relates to 300kWp up to 10MW projects). Projects outside this can also be funded but will be treated on merit, on a case by case basis.
    • The SPPA has to be with a bankable private off-taker for self-consumption – optional financial security is project and client dependent.
    • For International PPAs, LTM prefers to contract in USD currency.
