Questions about PV solar panels
Feasibility?
The UK has around 50-60% of the sun's radiation of the equator.
Add your annual energy/fuel costs x 30 years (panel lifespan).
Add 3-5% yearly inflation = approx future energy costs.
Compare this figure to the cost of installing a PV system.
Solar panels are ideal for people working from home.
How do PV systems work?
- PV cells are bombarded with photons, creating electrons.
- The Inverter switches the resulting current from AC to DC.
- The power will go to technology in your home first, then battery storage.
- Electricity generated will be recorded in the management system.
What happens to my surplus power?
If it's not fed into battery storage, heating hot water, or EV-charging, then it automatically feeds out to the National Grid, and payment comes via an export tariff.
Why PV in cooler climates?
Actually, photovoltaics work more efficiently in cooler temperatures.
Degradation of the panels occurs much quicker in hotter climates, just like redlining your car engine will reduce its lifespan and efficiency.
Can PV heat my hot water?
PV-to-hot water converters heat traditional hot water tanks by using daytime solar-generated electricity redirected to the heating coil. This device eliminates the need for your boiler to heat water.
How much roof space?
Although PV-arrays take a lot of roof space, most homes in the UK are suitable. Additionally, they can be ground-mounted A-frames if a roof is unsuitable.
What does grid-connected mean?
Any excess electricity produced will be directed out to the National Grid, and you will be credited accordingly (if battery storage is not present).
Any deficit between in power generation automatically draws from your electricity supplier as per usual.
Do I need planning permission?
No planning permission is required unless on a listed building/conservation area.
What maintenance is required?
No maintenance is required because PV is a 'solid-state' energy conversion process with no moving parts.
Do solar panels work on cloudy days?
This answer depends on the density of the cloud. In average cloud densities, the sun can penetrate. With very, heavy dark, dense cloud cover, probably not. As an example, use a solar-powered calculator, and it will work fine.
Will the installation process have an impact?
Once the panels are fitted, the internal components don't take up much space inside. The overall installation process usually completes within 2-3 days.
Our installation partners are polite, clean and tidy.
How long does PV last?
Photovoltaics installed in the 1960s are still working today. Degradation is minimal consideration when choosing a system. Monocrystalline solar panels still have an 80% generation capacity after 20 years.
What about cleaning?
PV solar panels are coated with a microscopically thin layer of titanium dioxide during manufacturing. When ultraviolet light falls on the glass, the coating reacts with organic matter to break it down.
As NASA's Mars inter-planetary rovers, Spirit and Opportunity demonstrated perfectly, dirt and dust find it difficult to attach permanently.
With that said, a periodic clean, using de-ionised water, will ensure optimisation.
What are the costs?
The cost of a PV solar system depends on system size and plugin requirements.
A consultation can be arranged"The installation was completed in about seven hours with no mess or fuss. The installers were polite and very careful. The completed job was very neat and tidy. Since the installation, the panels have generated far more than we've used. I'm very happy with our new shiny panels and would not hesitate to recommend."
