10kW Solar PV system at Oakdale School in Poole

NGPS were proud to be asked to install the 10kW Solar PV system at Oakdale School in Poole. This system has Enphase micro inverters which have a 25 year warranty.

This work was completed as part of a £1.7million extension to the school, including six new classrooms built in a two storey extension at the school in School Lane, to allow admission numbers to increase in September when the new school year begins.

Micro Inverters vs DC Optimisers

Here’s some information on the differences between Micro Inverters over DC Optimisers that we think you’ll find interesting.

There’s been a lot of talk about the Solar Edge system lately and from their marketing materials you’d think their technology was the answer to a solar installer’s prayers. But there are four things that you need to know before you install a Solar Edge system.
First: DS optimisers have all the down sides over old technology plus some new ones. String inverters have a single point of failure and Solar Edge systems have a second, single point of failure. If either the inverter or communications go down, power production stops. Micro-inverters have no single point of failure and if a micro-inverter or the communications go down the system keeps on producing.
Second: Solar Edge is proven to produce less power. A third-party testing facility found Solar Edge produces less power than the world’s leading micro-inverter day in and day out. Why because while a single DC Optimizer may turn on at 5 volts the whole system can’t turn on until it produces enough power to get the inverted going, and that takes 350 volts or more. That’s why a system with the leading micro-inverters wakes up a good 30 minutes earlier than a solar edge system each morning and keeps producing later each evening.
Third: DC optimizes are more complex to design and install. And you have to juggle your design around their limits. You need fourteen modules per branch to get the best energy production. You can lose 2% or more power if you have fewer or more modules and if you have fewer or more eight modules, it won’t turn on the inverter at all.
Finally the efficiency and warranty that Solar Edge talks about is misleading it’s the whole system that you have to think about so you have to multiply the efficiencies of the DC optimizer and the string inverter to get the true efficiency and the warranty, the warranty of the whole system is only as good as the shortest component’s warranty and the warranty for Solar Edge string inverters is much shorter than for their DC optimizers. As a solar installer you want a system that makes power for your customer and money for you. When it comes to flexible design, high power production and system reliability, micro inverters win out every time.

Energy Prices set to soar, year on year

Are you worried about the never ending rise in energy prices?

As demonstrated in recent weeks with average 9% price hikes, the energy companies seemingly have a license to pick the pockets of the British public

If that isn’t depressing enough, the government’s go ahead for the new nuclear plant at Hinkley Point guarantees that at best, the wholesale cost of electricity will double over the next ten years!
That`s 10% a year and energy users pay the retail price which is a lot higher than the wholesale price.

Enough is enough I here you say, so why not take a stance now?

For a one off payment, using money you will otherwise hand over to those energy companies, a renewable energy source on your property offers the opportunity to fight back and inflation proof your family income against those frightening price increases.

Award winning ‘Best Installer in the South & South West’ Renewable and Electrical specialists NGPS, are offering home owners a free, no obligation property survey and quotation service, at the end of which you will know:

What type of installation is viable for your home.
What outlay is required.
And most important of all, what you can expect your Return on Investment to be.

Don’t delay…call us today!

NGPS and Dorset Energized

NGPS is partnered with Dorset Energized to help Dorset get energized and be part of the green revolution.
Dorset Energized are a non-profit organisation with the goal to educate people that renewable energy can save you energy and money, while also being a benefit to the planet.
They advise individuals, household, businesses and communities to invest in renewable energies to be more energy efficient and sustainable.

“We would like to help everyone feel informed about why renewable and sustainable energy is important. We would like to help everyone know what renewable technologies are available, and their advantages and disadvantages, so that you can have confidence in exploring the options that will work for you, and to take the next step. After all, there’s little point learning about how to install a small hydro-electricity system if you don’t have access to suitable running water.”
