“From the initial site visit to commissioning the work was carried out by a firm that didn't pressure you into buying something you didn't need or want and explained in a language that was understandable to a lay person.”

"… Earn money without any effort and receive a much higher rate of return than alternative Investments ..."


The Sunday Times put solar PV panels as one of its top five investments for making 10% returns on your savings.


In the article it advised customers to consider PV following the introduction of the feed-in tariff in April 2010, offering them a tax-free, index linked income for the energy they produce. The new coalition Government has agreed to honour the feed-in tariff system for electricity.


"Given that the income is tax-free, the return on investment is equivalent to 12.9% for a 50% tax payer and 10.3% for a 40% tax-payer, with the investment recouped in as little as seven years. As the payments are linked to RPI, this equates to a real return of 18.2% and 15.6% respectively at today's RPI rate of 5.3%"

The table below shows some guideline benefits on various rated system sizes. These are based on a retrofit installation on a south facing, un-shaded, 35 degree angle roof using medium efficiency monocrystalline modules.


We offer many other types of solutions and sizes of systems but the below table gives an idea of generation for a standard domestic installation with a string inverter.

There are many solutions available and the guide below may not suit your particular situation or requirements. If you wish to receive a more tailored estimate without having a site survey please contact us with some details of your property and requirements.


If the guide below or your individual estimate is acceptable, we would be pleased to arrange a technical site survey which will result in a formal quotation to meet your budget and requirements.


Based on an optimal PV system in London - further south will generate more energy.
