Every watt of electricity generated by your solar power system and used by you directly in your house will save you money, as you do not have to buy this electricity from your electricity retailer. Therefore it makes sense to use pool filters, manufacturing equipment, dishwashers and washing machines when the sun shines brightly.
For excess power generated and sent back to the grid you may get a feed-in-tariff from your energy provider. The amount paid to you for each kilowatt hour of electricity can vary between energy retailers. You should talk to your LG solar installer or call your energy company and ask them about their solar feed-in- tariff rate. In some areas not every electricity provider pays for the electricity you feedback. This is blatantly unfair, as the retailer then sells the electricity you generated and the retailer collected for free – to other consumers for a decent profit.
Your local LG solar installer can advise you as to the energy retailer which offers the best feed-in tariff deal in your area. Consider changing energy retailer if you can get a better feed-in-tariff from another company.
