Meyer Burger are a Swiss company, manufacturing in Germany and source their raw materials from Europe where possible, such as Wacker, Norwegian Crystals and Norsun. They further state that the balance of their polysilicon comes from South Korea.

Why is solar becoming so popular?

The main reasons for this are because you’ll be less reliant on the national grid for your electricity needs due to producing electricity on site via your solar panels, this electricity can be used right away or stored in a battery to use later.

If you go down the battery storage route (Which is optional and can be added at a later date) you’ll also be able to charge your battery storage unit during off peak hours from the national grid. For example, Octopus Energy are currently offering this service between 11:30 and 5:30 am at a rate of 7 pence per unit. Please note you will need a smart meter and EV Charger to access this rate.

Solar energy is also a renewable source of energy, therefore reducing the carbon footprint of your home.

Solar Panels and Solar Inverters

Solar Panels – Photovoltaic (PV) modules, often referred to as solar panels consist of a number of semiconductor PV cells connected together. They convert light energy into direct current (DC) electrical energy.

Current and power output varies with both the size of panel and light level up to peak output in full bright sun.

PV modules are connected to your home or business premises through an inverter to either power your property, to charge batteries or to send power back to the national grid. Sending excess power back to the grid will allow you to claim the Smart Export Guarantee.

Solar Inverter’s – Inverters convert DC (direct current) electricity generated by wind turbines, photovoltaic modules or stored in batteries into 230V 50Hz AC (alternating current) power required to run conventional appliances and for connection to the grid.

Battery storage solutions – use the sun’s energy 24/7

Battery storage is at the heart of self-consumption as it will allow you to make better use of your Solar PV system by better balancing the outgoing solar electricity and what you are buying from the national grid. This is because the excess electricity that is produced by your solar system will be stored in your battery rather than sending it back into the National Grid and buying it back later in the day.

Advantages of energy storage systems

Lower energy costs

Use more of your own solar power, draw less energy from the grid and save on costs.

Increase independence

With a storage unit, you gain independence from rising electricity prices.

Guaranteed power supply

If the grid switching device is installed and there is a power failure, you can supply your own solar power from the storage unit.

Use solar power, even at night

A photovoltaic system produces electricity during the day when the sun is shining. In a typical household, however, the electricity demand is highest in the morning and evening hours. This is precisely when little or no electricity is being produced.

In order to use as much solar power as possible instead of expensive electricity from the public grid, you can either postpone your energy consumption until the sun is shining, or store solar energy for later.

Backup power supply in the event of a power cut

Did you know that most photovoltaic systems are automatically disconnected from the grid and switched off during a grid power cut?

However, with an emergency-capable hybrid inverter, a battery storage system and a grid switching device, the PV system also runs when it is disconnected from the grid, and you can continue to supply yourself with your own energy during a power outage.

Our recommendation – Fronius GEN24 Plus and BYD Battery-Box Premium

Main advantages of BYD battery storage

  • Superior technology – Designed using one of the most reliable and safest battery technologies available, the battery is based on Lithium Iron Phosphate (LiFePO). This type of battery cell chemistry allows for more cycles (complete charge and discharge) over the lifetime of the battery compared to other technologies. It also ensures less degradation, so the battery can operate at optimum performance for longer.
  • Highest safety Standards – The BYD Battery-Box Premium meets some of the highest global safety standards including VDE 2510-50. The German energy storage system standard VDE-AR-E2510-50 is the strictest safety standard in the energy storage industry. The certification highlights BYD’s commitment to develop and produce some of the safest possible energy storage technology on the market.
  • Flexibility to increase – As your energy needs increase, so should your battery storage. The design of the BYD HVM battery provides homeowners with the flexibility to expand their battery storage in the future. Homeowners can increase their battery storage size in increments of 2.8 kWh for the HVM battery, taking the battery to a maximum of 22.1 kWh capacity.
  • Colbat (CO) free!

This combination has once again achieved top rankings at the Energy Storage Inspection 2024. The Energy Storage Inspection is carried out annually by HTW Berlin and is considered Europe’s most important study on the efficiency of PV storage systems. As part of this inspection, the duo made a great impression for the fifth time in a row thanks to their exceptional efficiency.

FAQs

How does solar pv work? Once your solar panels have been installed, they are linked to the fuseboard inside your property. When the sun is shining, your solar panels are producing electricity, this power is then used to power your home. It really is that simple.

How long does the installation take?
On average we find that 3-4 days is how long the installation will take from start to finish.

What does the Solar PV installation involve?
This will start with a site visit where we will discuss your needs and the layout of your property and tailor the installation to suit these requirements.

Once this has been agreed, we will book for the scaffolding to be erected the week before our electricians are due to start on site.

Next, depending on your roof covering, either our electricians or our roofing contractor will attend site to install the roof hooks, these hooks are screwed into your roof construction and are what your solar system will be fixed to, the next step is to install the rails and mount the solar panels onto them. This is the completion of the ‘on roof’ works.

Now the ‘internal’ electrical installation will begin, this is where our electricians will connect your solar system into the fuse board within your property. This involes running cables from the solar panels on your roof to the inverter and battery storage unit, which will generally be located inside your property either in the garage, loft or an unused cupboard. The inverter is then linked into your fuse board, much like the National Grid, which will allow you to power your home from your solar panels.

Finally, the system will be commissioned and we will issue you your MCS certificate, NICEIC certificate and notify the DNO of your installation.

Human Rights in the Solar Supply Chain

Recent reports have raised the concern that many UK solar projects and some of the world’s biggest solar companies use silicon that originates in China’s oppressed Xinjiang region, with a high possibility that forced labour has been used in its production.This is particularly prevalent within Solar Panel manufacturing. The solar panels that we supply have no link to XUAR or Uyghur region within China.

I recently decided to get solar panels. I then happened to run into Lewis Annear at Truro Golf Club.This company is a local businesses and I’m going to say they were the most professional business I’ve ever dealt with.From start to finish they were very informative. They knew exactly what I needed and were very helpful advising me of my options.The measuring up and fitting all went without an hitch. Everyone from the scaffolding team to the fitters were professional and courteous from start to finish.I was surprised at how affordable it was and I glad that I chose Simon Annear Solars.Thank you for a job well done. I look forward to saving money on my future electric bills and to helping the environment.

We had friends who had a complete system fitted by Simon Annear, and because of that we chose them having seen the quality of their work. We had air source solar and battery all fitted by this company and they are professional and courteous. When you buy a system like this, it’s not only the equipment and the fitting of it, but the after sales service which you should buy into. I have no qualms that we will be looked after in the coming years, and it was a good decision to have this setup and to have it looked after by them.

We had a 6.6kW solar array with around 16kW batteries and a 10kW Vaillant Arotherm heat pump installed by Simon Annear in September 2023. The introduction and design process was well managed and the installation was quick and efficient. Dates for installation were agreed and kept to. The heating / plumbing and electrical design work was well thought through and this resulted in tidy working practice and a very neat installation. The existing plumbing and heating which was slightly complicated was simplified and converted onto mains supply. Very happy to recommend this company.
