Factors that Affect Solar Panel Costs in Mandeville
The cost of installing a solar system in Mandeville can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The largest one is your system size, and other factors include equipment choices, financing options and the solar company you choose.
Solar Equipment
One of the most significant factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to spend about $3,800 per kilowatt in Mandeville.The model of solar panels and equipment you want is another factor that will greatly impact costs. Solar panels that are more efficient, like monocrystalline panels, tend to be more costly. Moreover, solar equipment goes beyond just the solar panels themselves. You’ll also need to make decisions about the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when looking into a solar system that falls within your budget.
Solar Financing Terms
Many homeowners find the average cost of solar in Mandeville to be prohibitively expensive, even if the investment pays off over time. Thankfully, almost every solar installer in the area provides financing options. Solar loans drastically decrease upfront costs in most cases, but they also lead to paying more over time due to interest.When considering your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying a higher down payment can lower the total interest paid over time.
Solar Panel Installation Company
Finally, the company you choose to install your solar system can play a part in determining how much you pay. Mandeville’s solar companies all have different labor costs and add varying upcharges to equipment. The size of the company sometimes plays the most considerable role in the cost. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have access to greater resources and better pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger companies.

How to Save on Solar Panels
The solar installer you choose will be a major factor in determining not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should take into account, such as:
- Contract: When looking through your solar installer’s contract, ask for clarification about any terms you’re not sure of and be sure you understand what happens in scenarios such as a system part breaking or the company going out of business.
- Solar Panel Brands: The kind of solar panel you’d like plays a part in which installer you should opt for, since different companies have different panels.
- Reputation: Your solar installer should have a solid reputation as a company and have demonstrated expertise in the field. Two ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from previous customers.
- Warranty: Companies typically offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
EcoWatch's Mandeville, LA Solar Cost FAQs
How much does it cost to install solar panels in Mandeville?
This is a tough question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $19,000 for a 5-kW system and $38,000 for a 10-kW system after the ITC is applied. It will cost more if you want other solar equipment or more efficient panels, or if you have higher-than-average energy needs. Conversely, you can spend less if you opt for a smaller solar panel system or less expensive solar panels.
Should I lease or buy solar panels in Mandeville?
Leasing solar panels can be an option if you can’t pay upfront or get a solar loan, but since you don’t own the system, you can’t take advantage of many solar incentives. Also your home value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most savings from going solar.
How much can I save on energy bills after installing solar panels?
It is possible to erase your electricity bills with solar panels, but for most homeowners in Mandeville, that will require at least a 10-kW system. Not all homes will have roofs that can accommodate that size system, so you’ll want to contact a local solar installer to see how many panels can fit on your roof.
How often do you have to replace solar panels?
On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger level of energy production.
