Just a very quick one today, as it’s a Friday.
Following a conversation with a customer yesterday, I just would like to very quickly clarify where your payback is coming from when you install solar photovoltaic panels.
- Primarily, your income stream is the feed-in tariff. This provides you with a payment for every unit that is generated by your system and you will be paid this whether you use it or not.
- Export of unused electricity forms the second stream. For domestic systems, and in fact all systems under 30kW, this is estimated as being 50% of everything your system generates. So in addition to your feed-in tariff income, you receive an export tariff for half of everything. It isn’t much in most cases – export tariffs are about 3p per unit at the time of writing.
- The third stream is money saved by using your solar-generated energy instead of expensive grid energy. This will always be more profitable than exporting and as export is estimated generally anyway you’ll get the same amount for it no matter what. Therefore, the more free solar energy you use, the more you save, the shorter your payback period.
Hope this helps.
