How much does cleaning solar panels improve their output?…read more I had my solar panels cleaned recently by @sudandsqueegie. I had them cleaned only a few months earlier by another company, but I recleaned them because two panels were producing lower output and looked obviously dirty. The other panels did not look like they needed cleaning. I was surprised to see that the cleaning improved the output of all the panels from an average of about 340 Wh per panel to about 540 Wh, an increase of about 58%! The first picture is a drone shot of the panels, showing the two panels that were obviously dirty. The first panel picture shows the output of all panels before cleaning, and the second panel picture shows the output after cleaning. The panel output measurements were taken within 1 hour of each other at around 1 pm. It was a partially overcast day, so the output is usually much greater. However, it shows the amount of improvement possible with simple cleaning of the panels, despite them not appearing obviously dirty to the naked eye. It turns out the two panels that looked obviously dirty had cracks in the glass surface, and most of the discoloration was dirt that had seeped underneath the glass coating and could not be removed by cleaning. Surprisingly, not only did the surface cleaning of the two "dirty panels" improve, but it also improved the other panels that did not look like they needed cleaning! The original company that did the cleaning used a brush on a long pole to drip deionized water onto the panels. @sudandsqueegee used a long pole with two rotating brushes, which seemed to be more effective. They were very efficient and professional in their work. I recommend them highly.

I used Shine Bright San Diego to clean my paving stone patio, getting rid of in-ground dirt,…read morediscoloration, weeds etc. I was serviced by Brooks, a very friendly and engaging gentleman. Here are the pluses and minuses of my experience. Pluses: * Rapid and courteous response to my initial request * Quick turnaround for an appointment * Quoted me a 2 hr arrival window, which they met. * Affordable service. * Patio is nice and clean and he cleaned splashes from the adjacent windows/ doors. Minuses: * I had told them about my pool right next to the patio, but Brooks didn't take any special attention to prevent some dirt and sand from entering the pool (e.g, putting down plastic film). Nor did they provide a method for cleaning it afterwards, which led to clogging the pump intake line, requiring a lot of effort on my part to clear. * On the patio itself, I needed to use a blower to remove residual stuff that the power wash didn't deal with. Ideally, they would have done that as part of the service. I would give them 3.5 stars if that was an option: I feel 3 is too harsh. 4 is probably a bit generous given what I needed to do afterwards. So, be wary if you have a pool nearby that they offer you a solution to prevent crap getting in it.

This most recent visit was another excellent experience. Eric arrived exactly on time, came prepared, and worked with impressive care from start to finish. He cleaned my windows and screens thoroughly and then pressure washed my balcony and garage. His work was meticulous--he took the time to do the details the right way and protected my floors and surrounding work areas throughout the job. Everything looked noticeably cleaner and refreshed when he finished. What I also appreciate about Ascension is their integrity and customer-first approach. It rained within a day of the window cleaning, and Ascension proactively rescheduled to re-clean the windows that were affected. That level of responsiveness and commitment to customer satisfaction is rare. I've used other window services in the past, and none of them compare to Ascension's quality and consistency. If you're looking for truly top-rate window cleaning and pressure washing, I highly recommend Ascension Home Services--and especially Eric for his professionalism and attention to detail.
