Buying solar can be a challenge to know what the cost is going to be and the time it will take to break even on the upfront costs of solar installation. At RenewSolar we believe that solar should work for you and be affordable. But more over it needs to be good value. Our target for large installations is a return in 4 year. The Solar installation in this post is available in the shop here.
We are like a charity and therefore we do not aim to make profits from you, this lowers the cost to you and we have a range of hardware that means that we can offer different price points and also fall within budgets and usually cost less than other suppliers. The kit here is a “standard” kit and we can often beat this price with our other offers.
For £5,500 you get a solar installation and a decent amount of kit which is both lower cost, but offers more than we can find else where on offer by a wide range of installers. but there are other costs to consider which could add to the costs. We did not include scaffold hire or other costs that may be required with your installation. its not so that we appear cheaper, but with so many different installs, there may not be the cost for some installations.
Sunsynk.
Sunsynk is a well known brand in the UK, it is also known as Deye other parts. The kit is a 3.6kw inverter which falls under the G98 installation requirements. this means you can install and then send notice of the installation, making the process quicker and also a lower cost.
We paired the Sunsynk inverter with Sunsynk batteries, two 5.32kWh Sunsynk batteries to be exact.
This gives you a little more than 10kWh of battery storage which is pretty good for most homes.
The flip side: While we can sell and chat about how good things are or could be, we also like to look at the down sides of any systems. it is not to put doubt in your mind or to upsell, but to give you an informed view from our experience.
The inverter is 3.6kw as a peak power output, if you are often above this power ( see power usage now on you smart meter) then you will only save what you have available. you may want a bigger inverter to cover peak periods or you will pay for the short fall from the grid.
The battery is 10kwh, which should cover the daily peak usage, but in winter when solar is not providing power though the day the battery will be used. it would be better to have 20kwh of solar storage.
The battery and matched system is not the most cost effective and adding more storage can be done, you will have additional costs as you would have to add additional hardware to add more battery packs.
In short the system will not be ideal for the family home but it will help lower the bills. Take a look for our other systems if you use more than 15kwh a day on average.
ROI and life.
We tend to think solar as a meets all needs and it is not, we looked at the ROI on the system and it is 4.53 years and after ten years the system will become warn but we would like to see a “profit” of around £14,000 before the system starts to fail, it should last 15 – 25 years, but we work on a lower number just to be safe and realistic.
Everything is covered by the manufactures warranty which differs from hardware to hardware. We also offer great support.
We did not include export sales, this is a thing for some and not others. but you can reduce the ROI by selling power back to the grid. There is a lot of different payments and plans that make a difference to the amount that you will get so we did offer a suggested amount with in the shop information on this system.
Why Bifacial solar panel?
In this package there are 8 solar panels, they are bifacial and this is for flexibility, they will work to a degree on a roof installation and could be used on a pergola, or ground mount or even a solar tracker system. The kit is designed for a roof installation and includes the hardware for this. But there are a lot of differences within each installation and its near impossible to account for everything.
imagine you want an installation in your house, but the other wants a installation in the garage. The costs here differ as we run cables to the main consumer units. So the panels being bifacial allows for a more flexible approach to where the panels will go for each person. Yes this does mean that the panels could produce more than 4kw.
How long from order to installation?
it could be less than a week, but it will depend on the installation and anything else that is needed.
Roof installations, vary from a cherry picker, to scaffolding hire, therefore we would rely on when those can be provided for the installation. if we say 3 weeks this would be a good starting point to work from.
Is the hardware mine?
Yes we do things a little differently. The hardware and installation are two separate things, Think of it as “goods and services“. When you order the hardware for the package, the hardware will be with you in around a week. its yours to do with as you please. They are the goods. The Service is the installation of the hardware which will follow and separate to the supply of the hardware that you need for your solar.
How long will installation take?
installing solar is fairly simple it takes two to three days for most installations. Complexity can add time to this, but we have included 3 days for the installation, other services may be required that we do not offer with this package. Such as trenching. You may find the roof is not suitable and needs work to take the solar panels. this is also not included, but is a service we offer.
Do you offer a installation warranty?
Yes, our work is warranted for one year and that the work is free from defects. but we do offer ongoing support past one year. it is a good idea to have the system checked (maintenance) on a yearly basis, we do not lock a warranty to us to maintain the system, so you can have anyone carryout maintenance.
