We didn’t take into account the full advantages of solar panels when we were designing Firecrest so we didn’t have them incorporated into the build. However Eric did foresee that we might retro fit them so we always had that option available. Last April, we stuck 4 flexible panels to the roof. Here’s what I wrote at the time
Being boaters, cruising took priority. Then a certain amount of fear and trepidation set in as Eric needed to drill holes in the roof in order to wire them in. Consequently that didn’t get done until we were laid up in Liverpool. We decided the best option to get the wires to the battery management system would be through ports drilled either side of the bathroom pancake vent.
With the wiring channelled out of sight, behind the calorifior and through the dinette seating to the controller under the dinette.
Ironically as shorepower was included in our mooring fee we didn’t reap the benefit from solar until we started cruising in late June. Eric has promised me and those interested that one day he will share all the facts and figures. Photonic Universe has been incredibly helpful advising and supplying our panels so last month we opted to add a fifth panel.
As all continual cruisers know getting deliveries to a boat needs a little creative thinking and frequently involves helpful family. This time it was my mum’s turn in their camper van to kindly provide an address and onward transport. The huge packaging was manhandled onto the boat and all bode well for us to install a few days later while moored at Appley bridge.
The sun was shining, the towpath was wide and our enthusiasm at its peak. We unwrapped our parcel and to our dismay discovered the panel was cracked. And it was a Sunday, no way to contact the company for another 24 hours. This was so frustrating, not so much the delay in fitting a new panel, but knowing we were well over the deadline for reporting a damaged in transit parcel, and when and where we would could organise a replacement.
As we have already said Photonics universe is a great company, and after a few photos and a bit of forward planning we realised the advantage of “the closed down canalside pub” … They still have good mooring, postcodes and car parks. Dover Lock Inn, is sadly one of those pubs, and Photonics pulled enough strings to organise both a pick up and drop off on the same day. This time the panel was inspected instantly and found to be in good working order
Although we had found a more convenient place to store this large panel, the weather was in our favour to stick it onto the roof the next day. We had opted to go for one larger panel rather than a further two more identical ones. The roof and edges of the panel had protective masking tape applied to help us stick it in place accurately.
Although the panel isn’t too heavy, it’s large and flexible so very vulnerable to being damaged. We practiced our manoeuvres several times before Eric was allowed anywhere near the glue. He uses CT1, which although it’s £10 a tube, (and we used 4) it’s waterproof, flexible and incredibly strong.
Together, we finally lowered the new panel into place, but you’ll have to take my word for that cause I couldn’t take photos at the same time. We spent a lot of time carefully easing out any air gaps and weighting it down with our 20kg boat ballast weights
All in all a very satisfying days work. Now I just have to find a CRT rubbish point where I can get rid of a colossal bag of card board. Cause right now it’s living in our shower.
Did I say getting rid of the rubbish was all that was left to do. Come back in 12 months to see if this new panel is wired in cause right now it’s just looking pretty and not earning it’s keep.
