Pros and Cons of DIY Solar Panel Installation

Solar is a trendy thing in 2016 and perhaps the most common question heard round the industry is “diy solar panels” – the concept of building a solar panel system by yourself. Of course, there’s a lot involved in a solar installation and there’s a right and a wrong scenario for do-it-yourself solar projects.

Going solar has major financial benefits: it reduces your monthly electricity costs and can even increase the value of your home. Incentives like the federal tax credit for solar can reduce your net cost by 30 percent or more, but solar is still a big investment, and the price tag can result in sticker shock. To save money, it’s no surprise that many homeowners are considering DIY. Below, we break down the top pros and cons that you need to know about DIY solar energy before making a decision as well as the DIY solar process.

The 5 step process to DIY solar panels

  1. Design and size your system based on energy needs
  2. Purchase your solar equipment (solar panels, inverters, racking)
  3. Install the racking or mounts for the panels
  4. Connect the solar panels to your racking equipment
  5. Install a solar inverter

Do it yourself solar panel installation can be less expensive, but your options are limited

According to data from the EnergySage Solar Marketplace, the average gross cost of going solar for homeowners (meaning your costs before incentives and rebates are applied) was $29,225. Of that amount, design and installation labor costs contribute about ten percent of the total bill – this ten percent is all that DIY solar saves you, since you’ll still have the buy the equipment yourself. Regardless, it’s still tempting to look into a build your own solar panel installation to save money and be in full control of your project.

Your solar energy system should continue to generate electricity for 20 to 30 years, so it’s crucial that you consider both the upfront costs and the relative financial benefits for all of your solar options. If you buy a home solar kit like the ones for sale at Costco or Home Depot, it may be less expensive per watt, but you aren’t getting the same quality equipment that solar installers are able to offer you. For the most part, solar installers buy from equipment distributors that don’t sell to the general public – and they’re often getting lower prices because they’re able to buy in bulk.

Pro: Build your own solar works for small off-grid projects

Most home solar kits are designed for off-grid use, which means you can’t use them and remain connected to your utility. If you’re an average homeowner, going off-grid is probably not in your best interest – being able to access utility-generated electricity is important if your solar energy system doesn’t produce enough electricity to meet your needs at all times of the day throughout the year.

However, home solar kits can be a good solution if you’re not trying to power your entire home. RVs, boats, and the increasingly popular tiny houses are all opportunities to explore do it yourself solar, because they are already off-grid and mobile.

On a related subject, DIY solar projects can be useful if you have a large property and want to power an outlying area, like a barn or toolshed, or want to easily install outdoor lights. In those cases, your electricity demands will be relatively low, so purchasing a small home solar kit and installing it yourself is feasible.

If you want to install a DIY solar project, compare several options beforehand. Grape Solar offers a few different DIY products for both grid-tied and off-grid systems, which you can find more information on below.

Con: Installing solar is complicated, DIY solar energy requires training and experience

When you decide to DIY your solar panels, remember that you get what you pay for. A home solar kit may be less expensive, but solar installers offer tremendous value for relatively little additional cost (remember that ten percent figure?). When it comes to installing an expensive electrical system on your property, finding someone who knows what they’re doing can actually save you both time and money in the long run.

Some of the best solar installers have been installing solar energy systems for decades – experience that no amount of online research or DIY guides can replicate. Every state requires that installers are licensed and qualified to install solar, and independent certifications like the North American Board of Certified Energy Practitioners’ (NABCEP’s) Solar PV Installation Professional Certification ensure that the company you choose to work with has an intimate understanding of the process.

Your solar installer will also help you complete and file the permits and applications that you need to submit to get your solar energy system up and running. This is particularly important because your utility won’t let you connect your system to the grid without sign-off from a certified electrician.

Because of your solar installer’s experience, they’ll also have a strong understanding of the financial incentives for solar available in your area, and might even be able to help you save more money by finding an incentive that you may have missed. Lastly, it is important to note that many equipment manufacturers will only honor their warranties if a qualified installer installed their equipment. Many installers will also offer an additional warranty on their own work too.

There are other (better) ways to save money on your solar installation

Of course, when making such a big decision for your home, you’ll want to find the solar option that has the greatest financial benefit for you. However, DIY solar energy isn’t the only way, or even close to the best way, to save money when going solar.

EnergySage data shows that solar shoppers who compare their options on the EnergySage Solar Marketplace save 20 percent or more off the costs of installation, as compared to shoppers who don’t compare quotes from multiple installers beforehand. The reason is simple: when solar installers compete for your business, you win! Considering that design and installation labor costs usually only make up ten percent of the cost of a quote, this means you can save just as much or more by simply comparing your options from prescreened solar installers competing for your business.

    My wife and I just bought a cabin that is pretty off the grid. We are really interested in putting solar panels on it for power. Thanks for mentioning that you should compare a few different solar options before deciding. You never know which one is going to work best for your particular situation.

    You claim 10% of the cost is labor, but the solar kits purchased through these vendors are often overpriced themselves.

    This for example, you can get a 2kw kit for 3000, 4kw kit for 6000, or 8kw kit for 12000 with unifi sunmax products

    That’s WAY cheaper than the numbers you claim for DYI

    In my research I have found that going solar is not worth it. I would like to just have a small system to run my high power users like my fridge, water distiller things like that but the cost of a system even if you make the entire system from scratch will cost way more than the savings on your power bill for many years and about the time you start to see the system paying for it’s self things begin to need replacing. Solar systems only work at full capacity in full sun, cloudy, stormy days it will perform quite weak. Going off grid or wanting to run things at night will require batteries, at this point there will be no savings. Batteries are expensive and only last between 5 or 8 years depending on how they were taken care of and the work load put on them. People don’t think of the cost of the system verses their power bills, they just think I want to lower my bill and stick it to the power company but it does not work that way. Think of how much the system will cost verses how many power bills that would pay. Here where I live in Sandy Utah even in the winter when I am using more power my bill never goes over $120.00 during the summer my bill is around $65-80.00 Just depends on where you live and if solar will be a good investment or not. If you have a remote cabin and you don’t use it anymore than once or twice a year it would be better to just use a generator and oil or battery lamps. Yes solar is the green way to go if your like most of us and want to help save the planet but the cost is also something to think about. Things to think about.
