How to build a cover for solar batteries?

[bara3]

I'm getting solar batteries installed on a wall at the front of the house. I want to build a frame that I can paint that covers the front and sides of the batteries so you don't see them from the street. I'm planning to leave the top open for ventilation. So from the top it will look like a u-shape

There will be a few batteries so I'm estimating the frame will be about 1.3 x 2.4m and maybe 50cm deep. If I build it from wooden planks would be quite heavy

What lightweight materials can I use for this? I want to make a frame that I will not fix to the wall so I can take them away if you need access.

Hi @bara3,

You can build a removable screen for the batteries, but the first and most important step is to confirm the required clearances with the battery manufacturer or installer. Many battery units have strict setback distances on the front, sides and top. Leaving the top open may not be enough if the manufacturer specifies a certain amount of free air around the unit. If the enclosure traps heat, the batteries can overheat, which can be both dangerous and extremely costly, so getting that guidance up front is essential.

Assuming the clearances allow for a screen, a good option is to build a simple timber frame and clad it with Merbau screening panels. They are durable, relatively light compared with solid timber planks and come in 1800 x 900mm sheets, which makes them easy to work with. If you divide the front into two separate panels rather than one large panel, each section will be manageable enough for one or two people to lift out of the way when access to the batteries is needed. You can lay the sheets on their side for the front and trim the excess to form the 50cm returns on each end. Because they are only 900 high, you will need to extend your frame upwards and add two rows of 140 x 19mm Merbau decking boards along the top to reach your target height of around 1.3 metres.

This type of construction keeps the weight down, gives you a neat finish and remains removable, while still providing the visual screening you want from the street. I've created the rendering below to assist with your project.

If you wanted to get the weight down further, you could utilise decorative screening, though a frame will need to be built to hold them upright.

Please let me know if you have any questions.

Thanks for that breakdown.

if I were to paint to match the back, which is cement fibre board but made to look like wood panel , would there be any other lighter options? I would also need something you can cut in store, so I think that rules out the Merbau screening panels. Can these be cut in store? https://www.bunnings.com.au/ekodeck-67-x-15mm-2-7m-greystone-classic-screening-composite_p0120984

In that case what about a different idea. I was going to store 3 Wheelie bins in front of that area as well. what about a structure to cover the bins? again just the front three sides.

but a DIY solution would have difficulty having opening doors at the front to move the bins out each week.

Hello @bara3 

You could paint the cement fibre board a timber colour, but it will not look the same as actual timber. I'm sorry but the Ekodeck 67 x 15mm 2.7m Greystone Classic Screening Composite can't be cut on the shop saws as it will damage the panel due to the size of the saw blade. I suggest cutting at home with a circular with a fine tooth blade.

In regards to bin covers, I suggest having a look at these discussions:

• Bin storage box by @ponting72 
   
• Bin storage shed by @annettespanski 
   
• Bin screening and timber mailbox by @cadsman 
   
• Bin cover

If you need further assistance, please let us know.
