Solar powered lights

[Travis Kelcee]

I don't really see the use case. The idea of off grid is attractive until you need replacement parts, food and other supplies or your neighbours see that you're the only house with lights.
To safeguard a grow a UPS to keep ventilation running (and odors low) is a cost effective solution. Plants survive days without light.
After 3 days without electricity there are other problems than weed.

Let me try again to explain it to you.

I live in the middle of nowhere. Neighbors and odors are not a thing for me. When we lose grid power it can take days to restore. So having a back up generator is essential to keep the lights, heat and appliances going where I live.

Most people use a portable generators or have a Generac type whole house generator installed. So they can have heat, lights, etc in the event of a blackout. We usually get a couple a year that last 24 hrs or more up to 10 days.

Portable generators are not designed to run continuously can use quite a bit of fuel.

An installed whole house generator with propane tank costs around $8k - $10k and use a lot of fuel.

My solar DIY backup generator cost around $9k, "fuel" is free.

Now if I had a portable generator or a whole house gen, using it in place of grid power to run a grow would be costly and stupid.

The same way it would be stupid not to take advantage of the free electric my DIY solar backup generator makes everyday.

Not sure why this is so hard to understand.

Unappealing in both appearance and character.

The 7 year playback period isn't.

Maybe if I hang a Taylor Swift mural over your'll find it more attractive.

Yea that makes sense but why design it to run a grow light? That is not essential and during a 5 day power outage there are higher priority tasks than growing weed.

If you look at my rough calculations regarding efficiency. At the high end you have 4 % efficiency. For 1 m² of canopy you need 25 m² solar panels. During winter 2-3 times that and if you want to compensate for cloudy days it takes another 4 times the space. That's 300 m³ at the extreme end.

So yea, it is hard to understand why anyone would turn sunlight into grow lights.

I recently got solar in the uk so did an experiment with my last grow to see if it was viable.

With a 6kw + 5.5kw battery, I was fine doing a modest 600w grow inside powering all fans and the occasional dehumidifier. The issue is that you need to run the lights when the sun is shining with a battery that small, so you’ve got the heat of summer and the heat of the lights which isn’t ideal. If we didnt have such a mild summer I’d have had heat issues.

Saved a fair bit on electricity though.
