February 22, 20215 yr I know several people on here have used the Nulok roofing system, but was wondering if anyone had used their PV modules? We are about to start renovation (including reroof) of a house with a double hipped roof and want to incorporate PV. Whilst in roof panels are the obvious option, the awkward shape of the double hipped roof means that in the absence of any manufacturers of triangular PV panels the flexibility of a system like this seems attractive to maximise how much solar we can get on. Would be interested to hear of any good/bad experiences.
February 23, 20215 yr Friends of ours built a house in 2011 and used Nu-Lok with their built in PV modules and have been happy with the system especially because they claimed the full FiT payments.
November 12, 20241 yr Hello, we are in Australia but interested in the Nulok system which is being promoted here. All the reviews I can find are well out of date. Does anyone have an up-to-date experience with Nulok? I’m particularly interested in the reliability and efficiency their solar tiles. cheers
November 12, 20241 yr Welcome to BuildHub @Accent Have you tried searching the forum for Nulok, ordered by most recent posts? It doesn't look like there's been a lot posted about the system in the last couple of years: https://forum.buildhub.org.uk/search/?q=nulok&quick=1&updated_after=any&sortby=newest
November 12, 20241 yr As a rule, PV slates are expensive and of lower efficiency than normal modules. They are a pain to wire up as well. Unless it is the only way (planning constraints), best avoided.

Unless it is the only way (planning constraints), best avoided. Nulok say that their panels (solar pv tiles) are 22.8% efficient, which seems to compare well with standard panels. Each tile comes prewired and they just plug together. They can have optimisers and or mini inverters fitted so are well suited to roofs that suffer moving shading. Here are the latest tech specs: https://nulokroofing.com/uk/wp-content/uploads/2022/12/Data-sheet-SolartrixE-1200-400-10volt-N.pdf

January 9, 20251 yr "Efficiency" does not matter. The only thing that matters is £ cost perk kW of generation capacity. How do lots of individual roof tile size PV panels compare cost wise to fewer large panels?

How do lots of individual roof tile size PV panels compare cost wise to fewer large panels? I wouldn’t say that the “only” thing that matters is £ cost per kW. Aesthetics and other considerations come into it too, such as robustness, longevity, reliability, fitting cost and time, ease of maintenance and repair, etc. Anyway, they said each kW costs an additional £1,195. Hopefully that helps.
