It has been 8 months since I installed my solar photovoltaic (PV) system, and I couldn’t be happier. Low electric bills and the pride of producing my own energy makes all of the hard work worthwhile. I climbed up to check out the system, making sure that everything is still tight and unaffected by the heavy rain season. Of course, like any installation with excellent workmanship, everything checked out fine. PV Systems are so trouble-free and maintenance-free, but even though I know that, I was still compelled to break out my ladder and head up to the roof to take a look. It got meRead More →

The heat of summer is still upon us, but fall has arrived and solar pool heating season is right around the corner! October 15th traditionally starts the solar pool heating season, but it seems to be getting earlier and earlier every year. The phone starts ringing off the hook as seasonal residents flock back to Southwest Florida and year-round residents find pool temperatures dropping. People like their warm pools — getting and keeping them warm is what we do! Shorter days and cooler nights result in significantly lower pool temperatures, especially for uncovered pools that lose lots of heat to the evening sky. Warm daytime temperatures andRead More →

You may have seen my recent post on how Florida utility companies are trying to spin the argument against Netmetering, the method by which millions of solar energy systems interconnect with the utility grid. The gist of the argument is that people who use less energy shift the cost of the grid’s infrastructure onto others. Of course, they don’t say it that way, but that is, in fact, what they are saying. I installed a solar water heater at my home yesterday. This solar energy product does not produce any electricity. It heats (or preheats) water to reduce the amount of energy used by anRead More →

I’ve seen homeowners do some pretty crazy stuff with their pool plumbing, but one thing that is quite common is finding valves arranged to slow down the water flow through a solar pool heater. The rationale given by people is that they want the water in the solar pool heating panel to heat up more before it gets returned to the pool. It sounds like a reasonable idea, but unfortunately it’s not the right way to maximize the performance of a solar pool heater! Sure, it’s nice to stand by the return jets in your pool and feel that warm water coming off your roof,Read More →

While all of our installers do great work, I can often tell which installer did a job by the plumbing. Sometimes it’s the valve manifold at the pool equipment pad and sometimes it’s the roof work. While he likely trained the person doing the actual work on the roof, I’d call this a “Danny job,” recently installed in Cape Coral, FL. Because two lengths of solar pool heating panel were combined in this system, it required that a “common high” be installed. This entails making sure that the water leaving the shorter panels reaches the common high point in the system, which equalizes pressure andRead More →

Let me start by saying that the solar energy debate has nothing to do with solar pool heating or solar water heating, which are traditionally the bread and butter of solar energy products in Florida. This debate is about solar electricity (photovoltaic panels). There has been a rash of articles recently describing a brewing battle between utility companies and the solar energy industry in Florida. Things reached a boiling point when the Public Service Commission refused to hear PUBLIC comment on issues that affect the solar industry. (read that again – it’s true – and it’s shocking). On one side we have the investor owned utilityRead More →

Well, the match was great… A big win for the US team. Maybe Ghana should have let power lapse during the match… In case you missed it, I posted on Monday about how Ghanaians have a power shortage, and they “purchased power” from Ivory Coast to make sure TVs stayed on during the World Cup match against the United States. To tie this into solar power, I wanted to point out how Ghana can alleviate some (but not all) of their power woes – by installing solar panels, of course! Ghana’s power comes largely from capacity built up in a reservoir behind a dam. The Lake Volta reservoirRead More →

One of the subjects that often comes up at the start of a solar electric (photovoltaic) system conversation is whether the utility company will “allow” a solar energy system to be installed. Is Lee County Electric Cooperative (LCEC) solar friendly in Cape Coral, Sanibel, Marco Island, and the other areas they cover? While there are challenges, utility companies are generally bound to Public Service Commission Rules, including Florida’s Met Metering Rule, which give consumers fairly broad power to install customer owned renewable generation equipment. LCEC is no different, and it’s actually quite easy to get a residential or small to medium commercial system installed. In fact,Read More →

You’ve probably heard of high profile investments in solar by large retailers like Ikea, Kohl’s, Costco, and the world’s largest retailer, Walmart. These investments leverage the long terms assets (real estate) of the companies into income producing machines both inside and out. Coupled with various tax credits, accelerated depreciation, rebates, and other incentives, investments in solar make great financial sense for companies who have maximized interior square footage, but haven’t taken advantage of massive swaths of roof space. Walmart alone has installed over 65 megawatts of solar capacity to date. Susan O’Neal Gear of Upstream Insight has an interesting perspective on big-box solar investments. She hypothesizesRead More →

Today I am at Florida Gulf Coast University (FGCU) to see eleven teams that came from as far away as Key West compete in the second annual High School Solar Go-Kart Challenge. All carts feature a completely electric drivetrain and will compete in speed and endurance races. Powered by three photovoltaic panels and batteries, solar go-karts highlight both the simplicity and complexities of electric powered vehicles, and mirror the interest in street-legal neighborhood electric vehicles and fully electric cars like the Chevy Volt, Nissan Leaf, and Tesla Model S. Today is mostly sunny, which obviously helps in terms of endurance and speed. The event is co-hosted withRead More →

Unlike the southern tip, the northern end of North Captiva, FL, not accessible by land vehicles, actually has utility electric power available. Just like any mainland homeowner, this one wanted to offset increasing utility bills with solar energy. Working on an island is obviously a challenge, but our amazing crew pulled off this 4.6kW SunPower solar photovoltaic system in two days. This system is comprised of fourteen SunPower 327W modules, among the most efficient modules commercially available. Paired with a SunPower branded SMA SB-5000US inverter, this system is expected to cover the majority of this homeowner’s electrical consumption. The system was installed to meet theRead More →

Some in the industry call a solar pool heating system with a heat pump or gas heater a Hybrid Solar Pool Heater. I prefer to call it a solar pool heater with auxiliary or backup heater. The word ‘hybrid’ is a bit overused in the industry, and can be misleading. Nonetheless, pairing an auxiliary heat source with a solar pool heater can be an ideal solution for some people, especially those who demand particular pool temperatures year-round. If you want your pool a particular temperature all the time, and operating cost is a secondary concern (cost is rarely a complete non-issue), you might consider installing aRead More →

Did you notice your latest bill from FPL hit you a bit harder in the pocketbook? Effective January 2, 2014, FPL raised rates for residential customers by about 5%, caused mostly by increased fuel charges. This change, approved by the Public Service Commission, also increased the non-fuel base electricity charge slightly. The fixed customer charge remained the same. Bills with the higher charges are arriving in mailboxes now. Want to fight back? Fuel and non-fuel consumption is reduced by conserving energy or by producing your own energy with solar energy or other renewable energy sources. The best part about solar energy is that you shaveRead More →

My wife will tell you that I was screaming at the TV last night while watching an episode of CSI. I’m one of those guys that points out every little factual mistake in TV dramas. The crack team of CSI agents were trying to determine which home in a neighborhood was using inordinate amounts of energy to identify a drug grow house. They had obtained the “energy” usage of a neighborhood of homes, and identified a home that consumed 5,300 “kilowatts” in one month – a sizable amount of energy supposedly. The problem is, a kilowatt is a measure of power, not energy. It’s beenRead More →
