As energy costs rise, more people turn to solar energy to offset those costs. A solar panel system can reduce your grid dependency, allowing you to power your home with solar energy for some or most of the time. A 6.5 kW system has more than enough solar energy to power most homes, with some homes having enough energy to sell back to the grid in areas that allow net metering.
The average cost of installing a 6.5 kW system is $16,250 to $22,750, with most people paying around $19,500 for a 6.5 kW system using monocrystalline panels installed on the roof. This project’s low cost is $13,000 for a 6.5 kW system using polycrystalline panels installed on the roof. The high cost is $26,000 for a 6.5 kW system using bi-facial monocrystalline panels installed around the home’s perimeter with ground poles.
Many solar panels can construct a 6.5 kW system. The most common and standard is a monocrystalline panel. Low-cost panels may not be as efficient, meaning you need more of them, including polycrystalline and thin film panels. High-cost and high-quality systems can include different monocrystalline panels, including bifacial, which use solar cells on both sides, so you have higher costs but need fewer panels. Below are the average costs for a 6.5 kW solar panel system using panels of varying price and quality.
6.5 kW Solar Panel System Costs
|6.5 kW Solar Panel System (Material Only)||$9,230 - $11,050||$11,570 - $16,185||$16,640 - $18,460|
|6.5 kW Solar Panel System Installation Cost (Labor Only)||$3,770 - $4,550||$4,680 - $6,565||$6,760 - $7,540|
|Total Costs||$13,000 - $15,600||$16,250 - $22,750||$23,400 - $26,000|
|6.5 kW Solar Panel System Cost per KW||$2,000 - $2,400||$2,500 - $3,500||$3,600 - $4,000|
Many factors influence your system’s total cost. This includes the inverter type, with string inverters costing the least. It also includes where the panels are installed, with roof-mounted systems being the most cost-effective. Your state can also play a role in costs, with many states providing incentives.
6.5 kW is enough to run many homes. In some cases, you may have energy to sell back to the grid if net metering is available in your area. If you install a battery with this system, you may be able to run many of your home’s systems at night. However, a system of this size may be too small if your home has above-average energy needs or you plan to go off-grid. In this case, upgrading to a minimum of 7 kW may be necessary. The system type, sun exposure, and the energy you use determine whether this system is large enough for your home.
Depending on the number of watts each panel has, you may need between 17 and 26 panels.
Inverters are based on the number of panels. Your system may need one string inverter or between 17 and 26 microinverters.
Yes, this is more than enough for most average households, and you may be able to sell excess energy back to the grid.
The number of kilowatt-hours your system produces each day depends on several things, including the number of sunny hours there are each day in your area. Generally, the output equals 100 kW per hour of peak sunlight.
