If you have solar then you may have found your making too much power, you may have too little storage to keep that power you have made, and you may have a grid tied system where you cannot store any of that solar power.
Exporting solar power is fine maybe, as you may get £0.15 per kWh or you may be on a fit system and you don’t mind paying the £0.26 or £0.35 for each kWh?
Before you get excited at what the result of this article will show, we do have limited availability of the hardware, and with our batteries being such a great deal, you may have to wait a while for the battery. now with that out of the way, lets continue.
Back in the olden days of scam solar most people did not have the option for a hybrid inverter, the key sales point was that you would get around £0.40kWh for your produced power and that varies a little but it was a pretty good deal while getting ripped off for the cost of the solar hardware and your house having a contract on its head causing more problems. or you could have been scammed entirely by a company that’s gone bust and get nothing and still be paying off a debt.
If you are a little bit more modern, then you hear to make the most from your solar system, you want to store more power or add more solar to save more money.
Adding more solar can be worth it right?
Our little solution allows you to add two more solar arrays, if you take a look at this array its affordable as solar panels are cheap these days. the big issue is the installation of the panels but see if we come in cheaper here or your going to do the DIY route.
Most installations old or new install on the south facing roof, but with a “real” system you can have panels on the east and west facing too. You do get less performance in the winter, but for the 90 days of a lower performance over summer you actually boost the winter production. If you have solar you know that winter time needs all the boosts it can get. You may have a garage, want a solar pergola, either way a boost in solar for storage and self use or summer boost for selling that power to the grid.
Per kW of solar means that in summer your going to make around £1.50 per day, Thats around £412 per year per kW Therefore if you have our 3kW solar array package, then your likely to make over £1,000 per year
Add storage to save money?
If you were unfortunate to buy your solar installation from a company over the past few years you were probably short changed you may have found yourself stuck with a system that charges over £2,000 for a 5 kwh battery or more, but you have limited storage which was sold to you as a “but your export…” This limitation can be side stepped.
Our solution gives you back control and opens up the options for you. but using standard batteries. Our LFP batteries work with a wide range of inverters, so you can add the battery to most systems. its not often as simple as picking anything up and putting it in, but there is little to stop you doing this.
If you have a grid tied system or a FIT system, its not going to give you power after the suns down. your Fit provider deducts money for this which you lose on export, then you pay again for the power back over night and in the evenings.
Fit scam article is here if you want to read how they do it.
So our batteries are the lowest prices in the UK. you will find it very hard to beat the prices from anywhere, so we can say that the battery cost is £1650 and you can work out that 15kwh of power will cost you £0.26kwh so you will save £3.90 per day, but we will look at the solar saving (275 days) which is £1,075 per year.
Targeted return of 1.5 years.
Like all solar guys and actual humans with a family, the cost and value has to make sense, so as you have read, you can make around £2,075 per year by selling power and storing power, so the solution must make sence in that it pays for itself. We call this the ROI (return on investment) and we think that its a bit more than 1.5 years because of installation costs and we did not include the solar array costs as this solution fits a wider range of applications.
What is it and how do we do this?
Its rather simple. a retro fit AC coupled inverter. As your solar system works, it exports power to the grid therefore you can store this power, the inverter we supply had two MPPTs meaning that you can add solar arrays to the mix expanding your solar array and yields. It also has battery storage, so you can store the power into the battery.
Having two batteries from an existing solar array will make each system provide power, this is a matter of the CT locations on how the systems are power both with charge and discharge along with settings on each of the inverters.
if you have an inverter then the additional inverter may need to be applied for with the DNO, for other inverters such as sunsynk/deye and Victron you may not have to apply as the inverter systems can be “behind” the main registered inverter
We will be adding the packages that should meet most installation needs into the shop shortly, click here for the retro fit items within the shop
