What are the key benefits of a Solar PV system?
Once installed and commissioned, the system offers a long-term free source of electricity that is exempt from price increases. By installing a PV system you will be reducing your project's carbon footprint and meeting new building requirements. A PV system makes no noise, has no moving parts, requires minimal maintenance, has a lifespan in excess of 25 years and generates no CO2 emissions.
Where can I install Solar PV modules?
The location of your PV array (group of PV modules) is vitally important. The modules should receive the maximum amount of daylight possible, so it is not advisable to install the modules in situations where surrounding buildings or trees may cast shadows. The best location for a PV array in the UK is on a south-facing roof, but can also be fitted on non south facing roofs with a slight reduction in efficiency. (PV Panels can not be fitted on a north facing roof). If your roof is assessed to be unsuitable for mounting PV panels then this can be overcome using a frame system designed for both flat roof and ground mounted systems
How efficient is Solar PV in the UK?
The PV modules fitted by Energy Solutions only require daylight to work, and so will generate energy on cloudy days at a reduced output. The UK has similar weather patterns to Germany where PV has proved extremely popular given their tariff structure, which is now available in the UK.
What maintenance and cleaning do Solar PV systems need?
Energy Solutions fit Solar panels that are constructed using a self clean coating, so the requirement for cleaning is minimal, although it is recommended that panels are checked from time to time for debris.
What happens if there is a power cut?
Energy Solutions fit a completely grid connected system. So if there is a power cut, your project's system will automatically switch off. This is a safety measure designed to stop electricity being fed back to the national grid and to protect individuals who may be working on the power lines.
What size Solar PV system do I need?
It will depend on how much you want to invest, how much electricity you want to generate via PV, and how much south-facing, un-shaded roof space there is available on your project.
How much energy will our project need?
We will undertake a site survey to establish with you your project system requirements. Depending on this we can specify the size of system you will need to provide sufficient power levels.
What if the project produces more energy than it needs?
Whenever your panels are producing more electricity than your building is using, it will flow back into the national grid. Currently in the absence of a smart meter your electricity provider will assume a 50% export of what you generate. This will lower your end users electricity bills and ensure none of your green electricity will be wasted.
Do Energy Solutions Solar PV systems need batteries?
No, all Energy Solutions grid connect PV systems are connected to the national grid. In the night, when the cells are not generating energy, electricity is bought from the utility company in the normal way. Any excess electricity generated during the day - for example, when owners are at work - is supplied back to the utility company. Energy Solutions also provide Off Grid Systems that will provide backup power when there is a power cut by storing power in a battery bank.
