Foresight is 2020 – 3 compelling reasons to switch to solar this year

Financial success doesn’t happen by accident — it takes planning and foresight. When it comes to determining how solar will fit into that equation for you and your home in 2020 three compelling reasons are encouraging many to make the switch before the earth completes yet another migration around the sun.  1. The Federal Solar Investment Tax Credit If you’ve considered going solar over the last few years, you’ve no doubt come across the most lucrative environmental subsidy in America’s history, the Federal Solar Investment Tax Credit, or ITC for short. 2019 to 2020 saw the credit step down from 30% to 26%, causing a sudden rush of homeowners looking to lock in the rate before the year’s end. The same pattern will repeat again this year, with the ITC dropping another four points to 22%. The average homeowner stands to lose approximately $1200 by procrastinating another year to make the change.  The 26% Federal Solar Investment Tax Credit expires at the end of 2020 2. Increasing Electricity Rates Lost money in the form of a federal tax incentive isn’t the only financial motivation putting pressure on homeowners to install solar. Since 2008, the average electricity bill has increased by 29%. In some states, rates are rising fast as 2-6% per year, with utility companies passing on the costs of repairing their outdated grids and lawsuits onto the customer. The best way to ensure your utility spending remains consistent is by generating your power with solar.  To partially quote the famous 1967 film The Graduate, “I want to say one word to you. Just one word…are you listening?”  3. Batteries. Solar plus storage is gearing up to be the biggest game-changer and influential factor in the coming years. In states where net-metering is coming under attack, the ability for a homeowner to better store the power he/she generates for later use is finally coming into fruition. Add to this that some states are offering additional incentives to offset the costs of renewable batteries, and you’ve got yourself a winning combination. 4. Added Bonus Installing solar is now cheaper than ever, with the installation cost dropping over 70% since the last decade. Companies such as Planet Plan Sets have streamlined the process of getting municipal approval and government subsidies, making the project more effortless than ever as well. When you consider that utility bills are all but guaranteed to rise year after year, the 10 to 20-year investment in a solar system for a home has an ROI that easily outperforms keeping the money in a traditional savings account. It helps home equity and keeps monthly energy costs predictable. The...

Can Solar Power Your Air Conditioner?

Can Solar Power Your Air Conditioner?

Maybe your electric bills aren’t that bad, except for summer when you have to run the air conditioning. But you are the conservative type, so you set the thermostat at 80 degrees and suffer through it. Because of this, you don’t think getting solar for your whole house can help you. You would only need the solar for a few months and only for the air conditioner.  Is it possible to just get solar panels for your air conditioning and not for anything else? It depends on who you ask. There have been many solar companies over the years that have advertised solar powered air conditioning systems but what were they really selling? Some of them were selling evaporative coolers (also known as swamp coolers). Contrary to having the word “swamp” in their name, these types of cooling systems only work in the desert because they rely on evaporating water to cool the air. They have very low power consumption and can often be operated with a single solar panel. If you live in the desert and don’t already have an evaporative cooler installed on your house, this is not a bad option to save on air conditioning. But, chances are, if evaporative coolers work well in your area, you already have one and it’s already saving you money on your air conditioning costs whether or not it has the solar panel. Other companies advertising solar power for your air conditioner were really just selling standard grid-tied solar power systems but sizing them smaller so they only offset the usage of the air conditioner and not anything else.  There really is no practical way to only power the air conditioner with solar panels. If you really wanted to do it, you would have to separate the electric circuit for the air conditioner from the rest of your house. Then you would purchase an off-grid solar power system with batteries to make sure that the air conditioner always had power even when it was cloudy. After you set all that up, you will have paid a lot of extra money for all the battery equipment and when the air conditioner wasn’t running you have solar panels on your roof going to waste because you isolated them to only run the air conditioner.  If you are going to install solar, you might as well install the system to the whole house. First, solar panels produce a lot more power in the summer than they do in the winter so they would be working hardest for you when you are running your air conditioning. Second, most electric companies offer net metering on...

Service Panel Upgrades for Large Enphase Systems

Service Panel Upgrades for Large Enphase Systems

When planning your grid-tie solar installation you have to consider some things about your main service panel because that is where you are going to make your connection to the grid. The larger the solar system, the more likely it is that you will have to make some adjustments or upgrades to your service panel in order for the installation to be code compliant. There are also a few tricks that may get you out of doing that extra work. First, let’s discuss 2017 NEC 705.12(B)(2)(b) and 705.12(B)(2)(d). These code sections are the reasons why you may have to alter your main service panel in order to install your solar. These code sections describe what is lovingly referred to by solar installers as the 120% rule. The 120% rule says that for load side interconnections, 125% of the maximum solar output plus the rating of your main service breaker must be less than or equal to 120% of the busbar rating. This is true for all solar installations but we are going to do the math with the popular Enphase microinverters so we can get very specific. Example 1: You are installing 16 Enphase IQ7 microinverters which output 1 amp each. Your total maximum solar output would be 16 amps.125% of your maximum solar output would be 16 x 1.25 = 20 amps.Your main service breaker is 100 amps and your main service panel busbar is 100 amps.120% of the busbar would be 100 x 1.2 = 120 amps.Your main breaker plus 125% of the solar output would be 100 + 20 = 120 amps.120 amps is equal to 120 amps so you are just barely okay to install as is. Example 2:You are installing 45 Enphase IQ7 microinverters which output 1 amp each. Your total maximum solar output would be 45 amps.125% of your maximum solar output would be 45 x 1.25 = 56.25 amps.Your main service breaker is 200 amps and your main service panel busbar is 200 amps.120% of the busbar would be 200 x 1.2 = 240 amps.Your main breaker plus 125% of the solar output would be 200 + 56.25 = 256.25 amps.256.25 amps is not less than or equal to 240 amps so you can’t do a load side connection like this. If example 2 is your situation, let’s review your options. You can de-rate your main service breaker to 175 amps. This changes the math to 175 + 56.25 = 231.25 amps which is less than 240 so you are good to go as long as you can do some load calculations to prove that your house will be okay with only...

Choosing Solar Panels

Choosing Solar Panels

The biggest part of a solar power system is the solar panels themselves. With dozens of different solar panels in warehouses across the US, how do you decide which ones to get? There are many ways to compare solar panels so let’s talk about what to look for. Many people make the assumption that a solar panel with higher wattage is always the better choice, but this isn’t necessarily true. If you are comparing solar panels that are same physical size and one of them is higher wattage, that means it is more efficient and will cost more money per watt. If you have a limited amount of space to install your solar panels, then the more efficient solar panel would be a good idea because you can fit more wattage in the space you have. But if you have plenty of room for solar panels, it may not be worth it to pay the higher price per watt for the more efficient panels. Lower efficiency does not necessarily mean lower quality.      Which brings us to the discussion of quality. Determining the quality of a solar panel is not an exact science but there are some things you can look for. Looking at the manufacturer is a good idea. Ask questions like how long they have been in business and whether they make things other than solar panels. What you are trying to judge is whether or not they will be around 20 years from now to honor their warranty. If they have been making solar panels for a long time, chances are they are good quality or warranty issues would have put them out of business. If are a major electronics brand, that make other things chances are they will stick around and honor their solar warranties because they will still want to sell their other products. Another way to determine solar panel quality is check what certifications it has. You can see our blog article “Solar Panel Certifications Demystified” for more details but all solar panels have to be certified to meet the UL 1703 standard but they can also take it up a notch and get certified to meet other IEC 61646 standards for durability and performance or get tested over time for the DNV GL PV Module Reliability Scorecard which is what financial companies look at when investing money into solar farms. Solar panel manufacturers can also get their factories certified to certain quality standards as well for added peace of mind.  Some people get hung up on different types of solar panels. They might insist on monocrystalline solar panels because they heard they are...

Where Should You Install Solar?

Where Should You Install Solar?

Everyone knows solar panels can save you money, but where should they go?  First, let’s discuss location on a larger scale. There is no place in the United States where solar wouldn’t work. You might think you it is too rainy, too cold or you live too far north and don’t get enough sun but let’s drop those excuses.  There is no location that gets too much rain. Even in Seattle with 226 cloudy days and 38 inches of rainfall per year gets enough sun for solar panels to be worthwhile because solar panels will still produce electricity on cloudy days, just not as much as they would on sunny days.  Too far north is not a problem, but there are things to consider. Unless you are at the equator, solar is going to produce more power and in summer and less power in winter because of the angle of the sun and the amount of daylight hours. The further north you go, the more extreme this is. In Alaska, solar works great in the summer but it won’t do much in the winter. In the continental US, you will still get solar power in the winter and with most grid-tied systems you would be on yearly net metering billing with your electric company so it doesn’t really matter what month the power was produced. Many people think solar panels don’t work when in the cold, but they actually work better when it’s cold out. Cold temperatures can increase solar production by as much as 10%. The other side of that is really hot temperatures will lower production by 10% but that still means your getting a lot of free power from the sun, so don’t sweat it. So now that you know you are in the right geographic location for solar, let’s talk about where to install solar panels on a smaller scale. If you have a few acres of land you will probably have plenty of room for a ground mounted solar system. Even a half acre yard might have enough space that isn’t shaded by the house, depending on the layout. Ground mounts have advantages in that they are easier and safer to install (no lugging solar panels to the roof or worries about fall hazards) and you also have more options on orientation. You can check out our article on ground mounts vs roof mounts to get a better understanding of whether or not ground mounted solar is right for you. If your yard is small, then your roof will be the best place for the solar panels. Solar panels facing south will produce the...
