Solar FAQs
Angle of the panels: The tilt angle of solar panels affects their efficiency. Ideally, your panels would be installed at a 35 angle on a south facing roof to capture the most sunlight throughout the day.
Shade: If your panels are obstructed, shadows cast by trees for example, then the strength of the sunlight hitting your panels is decreased.
Cleanliness: Over time Solar Panels will collect dirt, luckily, they are low maintenance and only need cleaning a couple times a year.
Panels have warranty periods from 15 – 25 years and a working life output warranty of 25 years.
We base our recommendations on your roof space and orientation and your consumption of energy within your home. Each survey provides a tailored report to your home and lifestyle.
A Solar PV array with Battery Storage normally takes 2 days to install and commission. Larger arrays may take 2-3 days.
Yes, solar PV can be put on other surveyed roofs or even on the ground using frames designed for the job.
Nothing. Our design and installation take all of this into consideration using data provided by MCS – a governing body. We also consider manufacturer guidance for costal and high wind load areas.
Battery FAQs
By storing the energy generated from solar in reliable, powerful batteries, you can have a self-generated, renewable energy source. By storing energy from a cheap overnight tariff, you can reduce your electricity bills for use during the day.
Our hybrid battery storage systems are compatible with all solar panels so is ideal with retrofit applications. We can replace your ageing inverter with a state-of-the-art hybrid which will work with your existing solar installations.
Our battery storage systems will operate with Solar PV if you are off the grid.
Yes, our systems can be set to enable to charge the battery with energy delivered from the grid at off peak times, and automatically transfer to battery power at peak times.
Charge Points FAQs
EV – Electric Vehicle. EV tends to be used to cover all electric vehicles.
PHEV – Plug-in Hybrid Electric Vehicle. Mix of Electric and Petrol/Diesel, range of purely electric mode is limited to 10-40 mile.
BEV – Battery Electric Vehicle. 100% electric battery powered vehicles with ranges from 60 -300+ real life mileage.
EREV – Extended Range Electric Vehicles. Hybrid vehicles where the electric motor always drives the vehicle. When the battery reaches a certain minimum level, the combustion engine kicks in to charge the battery providing the extended range.
At home a 7kw charge point will take around 8hrs to charge a 60Khw from zero to full. Rapid chargers can deliver an 80% charge in as little as 30 mins, just enough time to recharge your batteries in the coffee shop!
You can get a grant up to £3500 towards a new vehicle and a grant’s up to £600 to install an electric charge point at home. EVi will take care of the grant application side in respect of charge point installation.
You will pay between 2-3p per mile on electricity as opposed to 10-13p per mile for petrol and diesel. With less that could go wrong with your car and less to service, your overall costs could reduce by as much as £2000 a year.
Be a prosumer
A Battery Energy Storage System helps you unlock the full potential of your Solar Array and gives you the freedom to control your energy and save money.
