Solar Photovoltaic cells are often advertised as an investment that saves you money in the medium/ long run. Let’s consider a a house in East Anglia, The average home electricity power use is;
2,900 kWh per year, priced at 28.34p Per KWH, £822 Per year electricity charge for metered electricity. (According to OFGEM)
Now, the house has a standard concrete roof, tiled, facing South, no Shading, standard
4.0kw (11 Solar Panels) generating 3,600kwh Electric per year;
2,900 kwh (we will use electricity per year )x 28.34p = £821 Per Year
4.kw Solar PV cost £4,995, pay back 6 years + Added re-sale value to the property + added protection of future increases in electricity costs.
If you have fixed your tariff until 2023 in favour of potential future savings as energy sky rockets in price, the maths looks like this,
2,900 kwh per year x 40.0p = £1,160 cost of 4.kw Solar PV £4,995 pay back 4.3 years pay back + Added re-sale value to the property + added protection of future increases in electricity costs.
we can add electricity storage systems, divert solar energy to the hot water emersion if you have a tank for hot water. The above is a simple example and reflects good conditions, so tell us about your situation and we will do the maths for you to check.
