The free solar panel option sounds too good to be true, doesn’t it, but in reality it is a fantastic option for those people or organisations who do not have the capital to outlay on a purchased solar PV installation.FREE-or-Paid-Solar-PV-Installations

So What’s The Catch?

With a free solar PV installation, the panels are installed on your roof and you can use them for your electricity requirements on a daily basis. You should see a significant reduction in your electricity bills.

With a free solar panel installation provided by Sustain you will not receive the full benefits of the government backed feed in tariff, Sustain effectively lease your roof for this purpose and will receive any benefits from the feed in tariff.

On the other hand, if you purchased a solar PV installation from Sustain, not only will you benefit from a reduction in your electricity bills, but you will also benefit from the feed in tariff, which is guaranteed by the government for 20 years. While there is an initial outlay involved, the financial investment is potentially more lucrative, however it is dependent on whether capital is available for your project.

Whichever solution you choose, sustain is on hand to deliver accurate and timely information to help you make the best decision for your circumstances. See further information on free or purchased solar PV systems.

Is Your Property Suitable?

When we review your application we have to consider the suitability of your roof and this involves an initial check using our desktop survey team who will assess your property using Google Earth. We check to see if your roof is the right shape, direction and has sufficient space for a solar photovoltaic system.

For optimum performance the roof should ideally be facing due south but other orientations will deliver good performance such as a SW or SE orientation. On a site visit Sustain will confirm the roof structure is strong enough for solar PV and will also check for shading that could affect the performance of the panels. See more on your properties suitability for solar PV.

Thank you once again.

I would really appreciate it if you could let your Management know of the exemplary work that has been completed. Thank you.


Rob White – Chorley

It has been a pleasure to deal with Sustain and their whole solar pv team. All the information has been explained in detail and we felt at ease with the service process. The electricians and roofers deserve lots of credit for their speed and precision to deliver what is a very neat and tidy installation. The team were hardworking and efficient throughout the installation process. It’s been a pleasure to deal with Sustain and as such I would have no hesitation in recommending them to others.


Clare Rogers – Manchester

The electrician and other contractors arrived on time, introduced themselves and spent time explaining the process as well as the scheduling. It was raining very heavily during the whole period of the installation and it was therefore very difficult to install the panels. The team did not moan about the weather, they just carried on regardless to complete a fantastic job.
