Expert Shalford residential solar energy solutions
At Zion Energy, we’re here to help our clients increase their energy independence. Our experienced assessors carry out energy audits that get a thorough look at your home - from how warm and airy it is, to how efficiently your appliances are working. This methodical approach allows us to develop smart plans to boost energy efficiency.
Our team can provide meticulous design of residential solar power systems. We help select the best inverters and panels to use and determine the best way to lay them out on your roof for maximum power output. Every project kicks off with a survey of your roof's structure before we get to work on the fit, installation, and ongoing care.
We also go the extra mile to help you get even more efficiency out of your system by offering innovativebattery storage solutions. While these are perfect for giving you the independence to run off your own solar power, they also make excellent sense for homes that aren’t set up for panels - you can cut your utility bills in half by storing up power during cheaper periods and using it when it costs more.
Our team will walk you through every step of the process, so you can be sure your home is equipped with a system that is tailored to your needs and ready for whatever the future brings.

Do Solar Panels Reduce Your Bills?
With rising energy prices, Guildford homeowners are turning to green tech, like solar and batteries, to help bring their electricity bills back under control. However, is solar really the best way to save on your bills?
A solar PV system will reduce the amount of electricity you need to import from the grid. The % of the energy your home uses from your system's annual production is known as 'Self-Consumption'. For homeowners in Guildford and Merrow with higher usage (>5000 kWh/yr), you are likely to have a higher self-consumption rate.
Self-usage is only one way solar and battery installations are saving Guildford homeowners. There are 3 main ways in which a solar and battery system can save you money, so let's have a look at each of them.

Using Solar Generation Directly
The basic way a solar and battery system saves you money is when the power you produce is used directly. Every time your home is powered by the power your solar panels are generating is a kWh you don't have to buy from the grid. Whether this is directly or via your battery, your solar self-consumption is the main way solar reduces your energy bills.
A typical UK Home will use 20-30% of the solar power it generates, which rises to 70-80% with battery storage. The higher your self-consumption, the higher your savings will be because import prices (electricity you buy from the grid) are higher than export prices (electricity you sell to the grid). Therefore, you save more by using your own generation than you earn from selling it to the grid.
The Smart Export Guarantee (SEG)
Selling back to the Grid. The Smart Export Guarantee (SEG) ensures that your energy provider has to pay you for the energy you export. Fortunately, you can shop around for the best deal, ensuring that you earn good money for your excess generation.
At the beginning of the SEG, export rates were pretty bad (3-4p/kWh). However, now you can get higher export rates of 12p/kWh. This means that solar panels alone are often financially viable and a good investment, paying back in 7-8 years.
Does this mean that battery storage should be avoided? The simple answer is no. A solar battery will increase your self-consumption, energy independence, and access to time-of-use tariffs gives UK homeowners more ways to decrease their savings.
Load Shifting With Smart Tariffs
The final money-saving avenue we will look at is load shifting. This is one of the best ways to increase your bill savings and utilise your battery to its full capacity.
For most UK homes, it is impossible to go off-grid as solar production is significantly lower during the winter months. Therefore, if we are going to have to buy from the grid, we want to make sure it's at the lowest possible rate. Load shifting is how we do that!
Load shifting is when you charge your solar battery with cheap electricity from the grid for use around your home when import prices are higher. This is most effective with EV tariffs, like Octopus Go or E.On Next Drive, as they offer cheap electricity for a short window overnight.
