The Future for PV is looking even better now the cost of the panels is lower, the cost has been dropping steadily over the recent years. The Feed in Tariff (FiT) started in 2009 at 41p/kwhr and with a 4kw peak system costing around 18,000 the return in investment was between 8% and 10%. Roger Budgeon from Greenshop Solar says Three years on, the return is still as good, despite the roller coaster ride that everybody has had during this period.
- PV is still a good investment, from the FiT alone, with a 4kw peak system costing between 8,000 and 10,000 (using quality panels), with 21p/kwhr payment a return on investment of 6-10% can be achieved. In addition to this if you use the power whilst the system is generating it saves importing energy, saving money and carbon emissions.
- The UK achieved over 1Gigawatt peak of generating capacity in January this year, and this is rising fast.
- If the building has a PV system already installed additional panels can be added if space is available, these panels will only attract the FiT rate applicable at the time of installation, not the rate of the original system, but with energy costs rising the extra energy generated is free for you to use.
- If your concern is maximising your use of the solar energy you can install a different type of inverter with batteries that will store the solar energy harvested in the day and supply it for use during the darker hours.
- Another issue is energy security, when the grid electricity supply fails the PV system shuts down, an alternative is again a different type of inverter and batteries that act as a backup supply. The length of time the backup supply will last is dependent on the number and size of the batteries. It is important to secure a supply for the heating controls, the fridge, freezer and lights, if these continue in times of power cuts life is not too difficult.
- One new hurdle that owners of new systems have to achieve is that the building that is connected to the system must be reasonably energy efficient, it must achieve a Energy Performance Certificate (EPC) level D or above. This can already be met by about half of the homes in the UK, those that cant, will be required to upgrade before they register for the FiT to get the full tariff or accept a lower payment level. The PV will help towards that EPC rating.
