You can generate cheap, green electricity from sunlight, even here in Britain.
Solar electricity systems capture the sun's energy using photovoltaic (PV) cells. The cells convert sunlight into electricity, and this electricity can power your lighting and appliances. You can receive payments for the electricity you generate, as well as for exporting any electricity you don’t use to the grid.
The cells used in solar panels are now so efficient that they will work well anywhere in Britain particularly if you have a southerly orientated roof. A typical home PV system can produce around 50% of the electricity used in an average household per year (Department of Energy and Climate Change), saving around £140 on your electricity bills.
In 2010, the government introduced the Feed-in-Tariff scheme to encourage uptake of solar panels. Under this scheme, your energy supplier pays you for any energy that you generate using your solar panels, as well as any excess that you export to the grid. The average installation can make around £420 a year in FITs at current tariff rates. You can alternatively get the installation paid for using a loan from the Green Deal finance scheme.
Fitting panels is not a complex process, and you can get them fitted with very little disruption. You do need to ensure that you get a qualified installer to qualify for the FITs.
- Will my roof be strong enough to take a solar PV system?
- Check this with your installation company as he should be able to confirm when the survey is completed prior to installation (they must do this before starting any installation). The majority is roofs are strong enough to take the weight of solar panels but should you need any extra reinforcement, you should factor this extra into your calculations and payback.
- What is a kWh?
- A kWh is a was to measure electricity, particularly electricity that is generated by your renewable energy system. A kWh or 'kilo watt hour' is often referred to as a unit of electricity that is shown on your electricity bill. If an electrical product has a rating of 1 kW it means that it will consume 1 kWh every hour that it is on.
- Are solar PV panels fragile?
- Solar PV panels are very robust; they are designed to withstand the normal stresses and strains subjected to them by nature. You can ensure that your panels are robust by purchasing only MCS accredited panels.
- Will solar PV panels affect my home's rateable value?
- Council tax is based on the 1991 values and the government shelved plans to revalue all houses a few years ago, so currently, no. It is likely that there will be a revaluation in the not so distant future. When they do, the value of the solar panels will be included in the valuation, but the rating could also account for your home's the Energy Performance Certificate (EPC) which should reduce tax as you would have a lower EPC score.
