Harness the energy from your solar panels for on-demand use.

Our solar panel and battery storage systems provide households with energy freedom.

Energy Security

Store your solar generated energy for use when you need it, not when you don’t.

Save Money

Storing energy for use at peak times means your need to use grid energy minimises, saving you a lot of money.

Scalable Systems

Grow your battery storage system to take advantage of additional energy or to facilitate higher consumption.

Solar panels with battery storage

Battery technology has developed at breakneck speed over the last decade. When solar panels first became popular, battery storage wasn’t a serious option for most households and remained in the sphere of hobbyist or environmentalist. This is no longer the case with many options for battery storage available either as an addition to an existing solar pv installation, or for those new to solar, as an entire energy production and storage system.

At Big Green Solar, we supply and install complete Solar Panel and Battery Storage solutions for homes across Wales and the West. We work with specialist manufacturers and high quality products to deliver robust solar energy systems fit for the 21st Century.

Is your property suitable for solar?

As part of our comprehensive FREE survey and quotation, we will guide you through the requirements of solar pv.

Structural Analysis
The load bearing ability of your house, the pitch of your roof and it’s ability to deflect wind are all major factors to determine the suitability of your house. It’s not uncommon for a property to require minor strengthening before we’re able to fit solar panels.

Shade Analysis
We conduct tests to ensure the maximum amount of sunlight is absorbed and how much shade your house experiences during different times of the day and year. This can affect which hardware we recommend and allows us to calculate potential output and savings.

System Recommendation
Based on the data our survey reports, we’ll be able to recommend the best system for your property. This will include the cost of the system, it’s specification and projected break-even timeframes.
