If you are eligible to receive FITs you will benefit in three ways:
In the case of a typical domestic solar array up to 4 Kwp , your "deemed export rate"
estimated at 50% is actually very generous. Your export energy can be diverted back to
your home for other uses such as water heating , storage heating , underfloor heating
and a multitude of other applications. You can use 100% of your locally produced green energy at home,
yet still receive 50% export payments as the export is "estimated".
The situation changes if you are have a slightly larger solar array between 10 Kwp - 30 Kwp (typically 40 - 120 panels). Until recently , energy providers would not fit an "export meter" unless your solar array was 30 kwp or above. This meant that if you were exporting more than 50%, you were losing out.
It is now possible, if you know that you export most of your electricity, to have an export meter fitted for systems of only 10 kwp and above. Thus boosting your financial returns substantially over your 20yr period.
Energy companies who are more forward thinking, such as "Good Energy" can fit an export meter for a small one-off fee (typically £80) with minimal operations costs.
