How Solar Power works for Homes

We’ve put solar panels on the roofs of hundreds of homes, paying all the costs for materials, installation and maintenance ourselves which gives homeowners a supply of free electricity.

The panels turn sunlight into an electrical current. The current flows into an inverter that converts it from DC electricity to AC electricity that can be used in the house. The electricity is fed into the consumer unit, and is used first to meet the home’s needs. If the panels are producing less electricity than the home needs, some will be imported from the grid and charged for by the customer’s usual electricity supplier; if the panels produce more electricity than the home needs, some will be exported back to the grid.

Customers can get a third to a half of their electricity needs supplied from the solar panels, with most of the electricity produced in the middle of the day.

We paid to put solar panels on hundreds of customers’ roofs between 2011 and 2015. We funded the installation and maintenance by taking a lease over the space above the roof to give us security for 20-25 years, and by collecting money for all the electricity generated in the house through the Government’s Feed In Tariff scheme.

If your house has one of our systems, and you have any questions, contact us here for more information or read our FAQs.

Information for Existing Solar Customers

If you already have one of our systems on your home’s roof, you should be saving hundreds of pounds a year from your electricity bill.

You should have a welcome pack sent by us when the system was first installed with summary information on how to use get the best from the solar panels and safety instructions for your electrician if you have work done at the house, as well as a copy of the lease over the roof space.

If you don’t have the pack, please email or call us to get another.

The equipment Green Nation has at your house:

• Solar panels mounted on a metal frame and attached to the roof structure
• An inverter – a box, often red in colour, with a small electronic display, mounted on a wall in your loft, garage or another convenient location in the house
• A solar generation meter – a small box, often grey, with a small electronic display that shows how much electricity has been generated by the solar panels. This usually sits next to the inverter, and is completely separate from your normal electricity meter that measures the electricity coming in from the grid

When Green Nation will contact you

We monitor the production from the panels daily at no cost to you by keeping a mobile SIM card in the solar generation meter.

We may need to contact you if:

• We are not getting any information from the generation meter, and need to check that the panels are still switched on
• We need to visit to clean or maintain the equipment
• We need to arrange for a meter reader to call at the house - this typically happens only once every few years

Occasionally, we may ask if you are able to go to the generation meter and take a reading for us. If the meter is in your loft and is difficult for you to access, please tell us that, and we will arrange with you a suitable time for someone to come to the house.

Part of the deal is that we will pay for the upkeep of the system, so if anyone contacts you saying you need to pay for a repair, they are not from us; don’t let them into your house, and please call us to let us know.If we need to send someone to your house, we will contact you first to let you know.

If you sell the house, please let us know the name of the new owner, and we will send them a welcome pack. Contact us here.
