Earlier in the spring of 2019 I completed my exterior home solar project. It's not grid tied, and its uses are limited to exterior dusk to dawn perimeter lighting, water feature fountain pumps, attic ventilation, backup power for phones with possible expansion for backup to my home surveillance / alarm system power backup and my boat battery charging system. I also made a portable 80 watt battery charger for camping which provides campsite lighting without needing gas lanterns or torches of any sort. 

 

Unfortunately shading from trees on neighboring properties and the orientation / design of my roof preclude a large system, and I'll never be able to grid tie but it's a very satisfying toy.  

 

Anyone else into solar power?

 

 

 

"I would advise you diy solar concentrator if you have small area."

 

I don't think they make fresnel / solar concentrator lenses for panels 100 watts and up? If they do, they may cost more than going up in panel wattage and changing over to monocrystalline which are generally smaller sized per watt than polycrystalline. 

 

Anyway, my two panels are a single 100 and 125 watt polycrystalline that's all I have room for without jumping up to and beyond 2x 200+ watt panels but as it is there's plenty of power for my needs. 

Im currently installing a 200k grid.
