Given the chance, we’d talk about solar power all day long. So we’re more than happy to answer any questions you may have.

Have a burning question about one of our technologies? Check this section to see whether it’s already been answered, and if not we’ll get right back to you.

We recently had a coldcall saying that the government offering grant on solar PV. Any truth?

The only grant currently offered for solar PV installations are the Feed In Tariff (where you are paid for energy your panels generate retrospectively) or through the Green Deal (where a loan is taken out against a property). Outside of these two grants, there is not a lot else offered by the Government.

If you have been cold called by a company offering free, or small payments on panels, it would be suggested that they send you literature on the scheme being offered, or contact the Energy Saving Trust for current grants.

Hello Im interested about having solar panels, but how do you know my roof is suitable without you coming out to see my property?

When we provide potential clients with solar PV options, we will first use a remote option. This means viewing your property from a satellite maps, like Google or Bing Maps. We take some measurements from these images and that will allow us work out, where you are, what direction your roof faces, and what will fit on your roof.

We can then email some options to you that will show the cost of the system to you, and how much you will earn back from the Feed in Tariff and also from bill savings.

Is there a standard weight in Kilonewtons per sqare metre for PV panels?

Each manufacturer has different weights for their panels. There is no standard, although it is more beneficial to a manufacturer to keep their weight low as to help with loading implications.

You can find more information about weights of panels on their datasheets.

Could you please tell me do you require planning permission or buildings regulations to have solar panels fitted oto my roof

It is only if your property is in an area that has had planning rights removed that you require planning permission. This will be areas like, areas of outstanding beauty, listed buildings.

If you property has not had it planning permissions removed then you can install panels without seeking permission, as long as they do not protrude over your roof, or are any taller than 200mm from your roof plain.

Do the panels create enough power to run a washing machine during the day without using the national grid

The average wattage of a washing machine is 700W, peaking at 2000W for heating (source). A PV system that is greater that 1kWp* will be able to supply the demand for the average wattage of the washing machine. If you did not want to use any energy from the grid then you would need a system that could manage the 2000W load, which would require a system of around 2.5kWp*.

* The system sizes mentioned are based on an output of a south facing roof, at 30°, on an average clear day.

Hi I have a big roof, and would like to put lots of solar on the roof, but don’t want to pay for an expensive grid connection. What is the biggest size I can have without a connection?

EvoEnergy only install  grid connected systems. By producing your electricity off-grid you would still get a feed-in-tariff payment but it would be significantly less than if you were on grid, and you’d also be missing out on the export payments.
