Learn more below on the Benfits of Solar PV and how it works
Solar PV works by converting energy from the sun into usable power. There are two forms of energy generated from the sun which can harnessed – electricity and heat.
Both are generated through the use of solar panels, which range in size from residential rooftops to large scale ‘solar farms’ stretching over acres of land.
Solar panels are constructed from semi-conductor materials, which are housed in a metal frame and covered with a glass sheet. When this material is exposed to sunlight, it releases electrons and produces an electrical charge.
This Photovoltaic (PV) energy creates an electric current known as DC (Direct Current). This DC electricity is then converted to Alternating Current (AC) by an inverter. AC is the type of electrical current used for appliances and lighting within your homes.
If there is a demand for electricity in the home (i.e. an appliance is switched on) the inverter converts the DC electricity to AC, then utilises this energy as a priority. If the Solar energy is not sufficient to power the appliance, the inverter will utilise energy from the Grid, to top-up the Solar energy.
If there is excessive Solar energy, i.e. low demand in the height of summer, the inverter will divert the energy to either a battery storage system or back to the grid (dependant on system configuration and components). This energy can then be stored in the battery for period's of higher demand and low Solar, or diverted back to the Grid (export). If you have a smart meter, then you can sign up to a Smart Export Guarantee (SEG) tariff with an electricity supplier, to be paid for any solar electricity that is exported to the grid.
This process is fully automatic and seamless, so does not require any human input to make it happen.
Yes, Solar energy is a renewable source. The conversion of Solar to energy creates no Greenhouse Gas emissions.
The Carbon footprint of Solar panels is already very small in comparison to other sources of energy, coupled with a life expectancy of 25 years, makes them a great option for reducing your Carbon footprint. Plus, the materials used in the panels are increasingly recycled, so the carbon footprint will continue to reduce.
Yes, Solar power only requires some level of daylight in order to harness the sun’s energy. The rate at which Solar panels generate electricity does however, vary depending on the amount of direct sunlight and the quality, size, number and location of panels in use. Utilising Optimisation devices can significantly increase Solar panel output in less than favourable conditions.
The UK is committed to reaching net zero by 2050. This means that the total Greenhouse Gas emissions would be equal to the emissions removed from the atmosphere, with the aim of limiting global warming and resultant climate change. Solar is a huge step towards the UK achieving this target.
Yes, you will save money on your electricity bill. How much you can save depends on the utility rates, the size of the solar system installed, how effectively you use the electricity whilst it’s being generated and if battery storage is installed.
