As a renewable energy consultant, I have been involved in the solar industry for several years and have seen the market evolve significantly. When it comes to the cost of a solar system, it is essential to consider various factors that can influence the final price. Let's delve into the specifics of a 10kW solar system and how much it might cost today.

Initial Costs and System Size
The cost of a solar system is primarily determined by the size of the system, which in this case is 10kW. This is a substantial system suitable for larger homes or small commercial properties. The size of the system will dictate the number of solar panels required, which is a significant portion of the total cost.

Solar Panels
The type of solar panels you choose can greatly affect the price. There are various types of panels available, including monocrystalline, polycrystalline, and thin-film panels. Monocrystalline panels are typically the most efficient and therefore the most expensive, while thin-film panels are generally less efficient but cheaper.

Inverters
Inverters are another crucial component of a solar system, converting the DC power produced by the panels into AC power that can be used in your home. The cost of inverters can vary depending on the type and quality, with microinverters and string inverters being common options.

Installation
The cost of installation can vary widely depending on the complexity of the installation, the location, and the labor rates in your area. Some companies may offer lower prices for the equipment but charge more for installation, so it's essential to get a complete quote that includes all costs.

Permits and Inspections
Before your solar system can be installed, you will need to obtain the necessary permits and have the system inspected. These costs can vary by location and the specific requirements of your local building codes.

Federal and State Incentives
The U.S. federal government offers a tax credit for solar installations, which as of my last update in 2018, was 30% of the total cost. Some states also offer additional rebates or incentives that can significantly reduce the cost of your system.

Maintenance and Warranty
It's important to consider the ongoing maintenance costs and the warranty provided by the manufacturer. High-quality systems will typically come with a warranty that covers both the panels and the inverter.

Financing Options
Many homeowners choose to finance their solar system, which can affect the total cost. Interest rates, loan terms, and down payment requirements can all influence the final price you pay.

Market Trends
The cost of solar has been decreasing over the years due to technological advancements and increased competition. However, prices can fluctuate based on supply and demand, as well as geopolitical factors that affect the cost of materials.

Conclusion
Given the information provided and considering the date of 2018, the average cost of solar was $3.14 per watt, which would make a 10kW system cost around $31,400 before any discounts or incentives. With a 30% Federal ITC discount, this would reduce the cost to approximately $21,980. However, it's important to note that these figures are from 2018 and may not accurately reflect current prices. It's always best to get a few quotes from different solar installers to get an accurate estimate based on current market conditions and the specific details of your project.
