It seems that almost every day there’s a new announcement from the energy companies that the price of electricity and gas is going up. What is more concerning is that they have warned that this upward trend is expected to continue for the foreseeable future.
No wonder then that the Self Generation market has experienced significant growth over the last few years, especially in home installed Solar PV, Battery Stoarge and Electric Vehicle charging points.
iHelios Energy Limited was set up to serve the needs of iHeliios customers as they provide the very best independent advice and service, as well as working with the No1 leading product manufacturers in the sector. But how do Solar panels work?
Solar panels have been around for many years, however over the last 10 years they have become much more efficient in capturing energy from the sun through their Photovoltaic cells (PV).
These cells use sunlight to generate energy, and even on a cloudy day, can generate a surprising amount.
The energy generated is converted into electrciity which is measured on kilowatts peak (kWp). This unit of measurement determines how much electricty is generated when the system is operating at peak performance.
In the UK, the standard permitted size of a domestic system is 4kWp, though this can be increased if permission is granted by your regional District Network Operator (DNO) of which there are 14 in the UK.
The price of solar panels has reduced significantly, so you can begin to generate your own electricity for as little as £2500 for a complete 2KWp system.
There are a variety of compenents requried for a solar pv system however the main 2 are the solar panels, which on average have a power output of circa 265 watts, though can range between as little as 225 to more than 350 watts, and an invertor which converts the direct current, DC, electricity generated by the panels into alternating current, AC, requied for appliances in the UK.
If you are thinking of having a battery storege system, either initially or at a later date, you will require a Hybrid Inverter, or what is sometimes knows as a multi-mode inverter, which simultaneously manages the inputs from both solar panels and a battery bank, so can change the batteries from either the solar panels or if neccessary, the electrical grid system.
This is a great solution as in the winter months, when there is less natural light, your solar panels might not produce enough energy to fully charge your storage system, so by having a duel fuel tariff, you are able to top you your batteries overnight, at a much reduced cost.
