Solar is the topic where the general answer and your answer diverge most. Panels behave the same way everywhere. Roofs, shading, electricity use and tariffs do not, and those are what decide whether a system earns its keep.
Eco Connect Services is an independent advisory business. We do not install. Where installation work is appropriate it is carried out by a vetted delivery partner, and the final technical advice and the quotation sit with them. Our part comes earlier: working out whether the thing being quoted for is right for the property, and what is worth establishing before you spend anything.
These guides cover how solar actually generates electricity in a home, what makes a roof suitable, how generation changes with cloud and season, how to read a cost and payback claim without being misled by it, what a proper consultation and site survey should cover, and how to prepare for one.
