Summary: While you could probably head to the BIG BOX stores and buy some common components, the kits come with everything you need to mount a single solar panel. After assembly, the angle of the panel can be adjusted without tools. This is particularly useful for RV applications as the panel is flat for transport and then tilted at an angle once installed in a temporary location. which allows installation with different hole spacing, which depends on my manufacturer. Recommendations: Bracket kits come in three sizes: 22", 28", and 45" (this review is for 45"). This kit has short legs that are 23 inches long and the panel can be oriented in either portrait (tall) or landscape (wide) orientation; the wide one is more stable and the tall one has a smaller footprint. Pros: good fit and finish; complete equipment. Cons: Cost (compared to buying off-the-shelf components and assembling the kit yourself); a newer offering with very few reviews (compared to the BogueRV kit below). Bottom line: $60 for a pair, 4 star rating. Related Items: BougeRV 41" Adjustable Solar Panel Mounting Brackets with Folding Tilting Legs $56 https://www.amazon.com/dp/B08DNQ92ZP
