Benefits of Solar Energy

Solar energy offers multiple benefits. Let's look at a few of them.

  • Reduced carbon footprint: Using clean solar power means you're less dependent on fossil fuels, which emit harmful greenhouse gasses.
  • Lowered energy bills: With solar panels, you generate power without paying the tacked-on costs of grid-connected power. Going off-grid can eliminate your bills completely.
  • Better energy independence: Solar panels can keep your home powered through emergencies and blackouts, giving you additional security. You can use your solar energy anytime with an optional battery storage system.

How To Choose the Best Solar Company in Longview

Choosing a company is the first step toward a well-oiled and cost-efficient solar system. Here are some essential aspects to remember while shopping for a solar specialist.

Licensing and Training

Solar energy installers in Washington must hold an electrical contractors' license from the Department of Labor and Industries. In some situations, the department may also conduct permit inspections to test compliance and the integrity and viability of a contractor's job. Solar providers can also obtain certificates from trade groups and standards organizations. The top ones in the industry come from the North American Board of Certified Energy Practitioners. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Longview

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power. Polycrystalline panels provide a lower price point but produce less power. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

Additional accessories, such as electric vehicle (EV) chargers and battery storage, will raise your overall costs. However, they might make your solar system more efficient and convenient to use. Not all solar providers include these additional features, so look for a contractor that installs them if it's a priority for you.

Generally speaking, it will cost about $17,950 for a five-kilowatt solar array in Longview. This table shows more specific prices for different solar panel types and system components in your area.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,071
Solar Polycrystalline $835
Thin-Film $488
Solar Battery $685
Solar Home EV Charger $2,570

Financing Solar Energy in Longview

There are various ways to pay for new solar panels, and the right one will lower your costs. A few of the most common options include power purchase agreements (PPAs), cash payments, loans, and leases. We suggest making a cash payment or securing a solar loan for the highest return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also own your system and can apply for solar incentives to reduce your total costs. Solar loans are another solid option if you don’t want to make a big initial investment. You can pay for your system in monthly installments while still enjoying energy bill savings and solar incentives. However, you’ll spend more in total due to accruing interest. Solar leases let you use your panels for a fixed monthly rate, while PPAs let you pay only for the energy you use, much like an electric bill. Both options disqualify you for solar incentives and don't grant you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Ask each provider you're considering about the payment options it offers. A staff member can help you determine the optimal option for your pocketbook.

The table below lists the average payback periods for different capacities of solar systems in Longview.

You can claim a 26% federal tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, local governments and utilities may have their own rebates and financing plans that could reduce your total cost even more.

Solar System Capacity Estimated Payback period
1 kW 2.5 years
2 kW 5.0 years
5 kW 12.4 years
10 kW 24.9 years
