Much has been written on the theory of renewable energy-generating technology in the home, but what about the practice? It is a misconception that solar electricity systems, which convert sunlight into electricity by capturing the sun's energy using photovoltaic (PV) cells, need direct sunlight. The PV cells can actually generate electricity on a cloudy day. However, the cells do need to be installed on a roof or wall that has an aspect that is within 90 degrees of south and is not overshadowed by buildings or trees. Any shadow on the cells during the day will decrease the output of the system.
Then there is the issue of attaching the PV cells. The cells need to be attached to either a roof or wall strong enough to take their weight. They are not light and you should check with a qualified installer before proceeding. If you live in an apartment and do not have roof access, then you will need your landlord's permission before mounting PV panels on the roof and connecting a cable from the panels to your flat. This is likely to be an issue with older, high-rise buildings.
Prices
As a very rough guide the cost of installing 1 kWp of solar electricity is approx. £8,000 depending on efficiency, quality and size. Also, PV panels that are built into a roof or mimic existing roof tiles will cost more than those that sit mounted on existing roof tiles.
To install PV panels you will need a MCS (Microgeneration Certification Scheme) electrician. The existing electrical meter will also have to be replaced with an input/output meter, and cable connections will be required from the roof to the meter. This will cause some minor disturbance to the fabric of the house, such as lifting of floorboards and drilling holes through walls. The homeowner will also be required to satisfy Part P of the Building Regulations (electrical safety), which will involve a fee.
Maintenance
Fortunately, PV panels need very little maintenance, other than being kept relatively clean and free from any shade from trees growing nearby. The wiring and components of the system need to be checked regularly by an MCS-qualified electrician, who will require access to the panels.
For many homeowners, location, property type, shading from trees/other buildings, etc. will make solar panels impractical as a green solution for their properties, irrespective of cost. An MCS accredited installer will tell you this at the survey stage, you will not be sold panels that do not meet your expectations of energy production & carbon reduction.
Urban Energy Warranty Scheme
Urban Energy are responsible for repairs and maintenance for the lifetime of the installation. The IWA insurance scheme, renewable every 5 years, covers your installation in the event Urban Energy cease trading.
The cost of the IWA warranty for first 5 years is included in your initial quotation, after 5 years we will offer an extension of five years to your IWA warranty which includes a service for £150.00 + VAT. This can be done every 5 years for the lifetime of your installation.
The equipment is covered by a manufacturers 10 year performance guarantee with a 20/25 year lifespan guarantee.
Urban Energy are a lifetime member of the IWA scheme our membership number is UAN.02.10.
