FAQ

How much space on my roof do I need for a solar PV installation?

Our grid connected systems start from around 1kW peak power; this occupies about 8 square metres on your roof.

How much electricity does a PV system output?

For every kW peak power installed on a South facing roof the system will generate around 800 kWh. This reduces by around 20% for an East or West facing roof.

How much does a Solar PV system cost?

Installed prices start from around £4,000.00 - £6,000.00 (Inc VAT) per kW peak power. There are no longer any grants available as these have been replaced with Feed-in Tariff (FIT)

Do I need planning permission?

Our roof mounted systems do not need planning permission unless the property is listed or in a conservation area.

Do I need to inform building control that I intend to install a solar system?

You should speak to building control about your intentions, and they will advise you if you need to take any further action with them. Be wary of any installer who advises you not to contact building control.

What is a kWh?

A kWh (pronounced kilo watt hour) is a specific amount of electricity. 1 kWh is identical to 1 unit of electricity that is shown on your electricity bill. An electrical item having a rating of 1kW will consume 1 kWh for every hour it is on at full power.

What is a Renewable Obligation Certificate (ROC)?

The government created an obligation for electricity suppliers to generate electricity from renewables sources. This system has now been replaced with the Feed-in Tariff (FIT)

What guarantees will I receive?

Panels generally have an output guarantee of between 20 and 25 years depending on manufacturer. Inverters normally have a guarantee of 5 years. Most other components and labour are usually guaranteed for 5 years. Check your quotation for specific details.

Are your panels & inverters approved?

We only use the very highest quality of materials. The panels we use meet all the required standards including TUV and MCS approval for government incentives.

Will an electrician fit the panels to the roof?

No, all roof work will be completed by our trained roofing specialists. Many companies use the wrong trade's people to fit the panels on roofs, we use our electrician for electrical work and our roofers for roofing work.

How long will the installation take?

Installation normally takes 2-3 days depending on size and access.
