Benefits of solar energy.

• Not dependent on fossil or nuclear fuels
• No harmful CO2 emissions
• Assured for the next 4 billion years, or there abouts.
• Supplies much more energy than is needed to manufacture the solar electricity systems
• If you covered 0.2% of the Sahara desert with PV modules, they would provide enough power to meet the world’s needs. (You would however, need some long extension leads.)

Solar PV stands for solar “photovoltaic” modules. Very simply, solar PV modules turn sunlight into electricity, and this is how:

• Every day, light hits your roof’s solar modules with photons (particles of sunlight).
• The module converts those photons into electrons of direct current (“DC”) electricity The sunnier it is, the more energy is produced by the modules.
• Those produced electrons flow out of the module and into a device called an Inverter.
• The inverter converts that “DC” power into alternating current or “AC” power. AC power is the kind of electricity that your household appliances use when they are plugged into the wall outlet.
• A meter keeps track of the all the power your solar system generates. Any solar energy that you don’t use immediately will go back into the grid through the meter. With the ‘feed in tariff’, you are paid for what you generate, even if you use it yourself, you still get paid. You also get paid considerably more per unit than you pay your energy supplier. Currently, you are paid according to the following;
  • Systems up to 4.0KW = 16p per unit generated
  • Systems up to 10.0KW = 14.5p per unit generated
  • Systems up to 50KW = 13.5p per unit generated
  • Systems up to 250KW = 11.5p per unit generated
• The ‘feed in tariff’ is guaranteed for 20 years & is also index linked to inflation.
• All PV modules used by Affordable Renewables, are MCS accredited so all carry a 25 year performance guarantee.
• Inverters are generally from SMA, Fronius, Power One, Mastervolt, Danfoss & Enecsys micro inverters.
• Mounting systems are generally from Schuco.
• If your roof is not at its best, we at Affordable Renewables, can quote you for a full re-roof using our in-house team. You could then consider ‘in roof mounting’ for a more streamlined look.
• Planning is not usually required. Listed buildings, ground mounted systems & some conservation areas may require planning. We can advise further at survey.

KWP = kilowatts peak.

KWH = kilowatt hours.

Savings on electricity bill due to energy used on site = Assumed 50 % @ (12.27p KWH) Carbon benefit = reduction in emissions as a result of solar generation.

NOTE: All figures are approximate & based on a south facing roof with an incline of between 30° & 45°. Reduced income would apply to other roofs. Most roofs between due east & west are still suitable but payback time is increased.

Energy companies pay an additional 4.5p for half of what is generated assuming it will feed into the grid regardless. Example. 1000kwh generated= £160.00+ additional £22.50 for 50% of 1000kwh of generated output at 4.5p
