However, the range of solar installation costs can be quite wide in Bethlehem, with typical prices between $20,000 to $40,000. There are numerous factors that significantly influence the price you’ll pay, which we'll go over below.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of going solar. Because of that, it’s important to accurately ascertain the size of the solar energy system needed for your home by figuring out your typical energy use.The brand and kind of equipment you choose for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
If paying for solar panels in cash is too expensive, solar loans are a popular route because they lower your upfront costs and let you pay for your system over five to seven years on average.Although solar loans make switching to solar energy more accessible for Bethlehem homeowners, they can also raise the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
The solar installer you go with to handle your switch to solar energy can play a role in your total costs.

EcoWatch's Bethlehem, PA Solar Cost FAQs
How much does it cost to install solar panels in Bethlehem?
This is a difficult question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $17,750 for a 5-kW system and $35,500 for a 10-kW system after the ITC is applied. You can expect to pay more if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy consumption. On the flip side, you can spend less if you want a smaller solar panel system or cheaper solar panels.
Is it better to lease or buy solar panels in Bethlehem?
Leasing solar panels can be an appealing choice, as it typically comes with low or $0 upfront payments. The drawback is that you won’t be able to save as much. If you lease, you don’t own the system, so you can’t claim any incentives and your home value won’t increase. Buying solar panels is a better way to go if you want to get the most savings.
Does Bethlehem have a net metering program?
The majority of states offer net metering programs of some kind. Through these, you can either receive compensation for the extra power your system produces or or receive credits to put toward future utility bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.
What solar power system size is right for my home?
The exact number of solar panels you need depends on your household energy consumption and the average daily sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to install between 20 and 35 panels to account for their typical energy usage.
