3 steps to installing solar panels

Step 1: Planning and Calculation

From your estimation utilizing the solar systems calculator, you can decide the suitable materials needed to install your system.

A few steps you can take to erect your system correctly include:
  • - Buying materials missing in your shipment
  • - Examining your shipment for loss or damage
  • - Evaluating safety rules for installing your system

Step 2: Wiring and Electricals

Wiring your electric run is a significant part of solar board installation, and functionalities differ based on the kind of panel you’re mounting.

This installation process involves planning the wiring run, grounding your board, and erecting a back feed breaker to link to the common grid, if required.

The wire length required for your design implementation will be outlined in your electric wiring diagram. As a general rule, the smaller the AWG number, the smaller the wire.

Step 3: Setting Up Your Solar Board and Battery Installation

Here are the five main steps you need to take to erect your system effectively:

  1. 1. On the roof area of installation, determine your roof pitch and mark the rafters.
  2. 2. Install roof attachments and racking rails
  3. 3. Lift panels onto your roof
  4. 4. Mount panels on your rails

When mounting your system, it is essential to factor in your solar board’s orientation. Pointing your panel in the most suitable direction helps your board receive direct light throughout the day.

Finally, ensure you consult the manufacturer’s instructions to erect your solar system properly. If you encounter any troubles, search for “solar installers near me” for professional help.

What are the typical savings when investing in a solar system?

The following steps will help you to effectively determine the savings when erecting solar on your property.

Determine average kWh consumption per month

You are likely to use more electric power in certain months of the year. Pick up your electricity bill for the past 12 months and use a monthly KWh calculator to evaluate your average consumption (kWh) over this period.

Evaluate your daily kWh consumption

Using a watt calculator, estimate your average daily kWh usage by dividing your monthly watt usage by 30. For example, if your average kWh per month is 1,200, divide that by 30 days (1 month), which results in 40 kWh per day.

You can then input this value into the solar systems calculator to estimate solar panel sizes that fit your home.

Estimate how much sunlight your solar systems receive

Sun exposure directly affects your solar power generation.

For photovoltaic boards, the calculator for solar panels’ angle tells you the optimum angle to get the most out of your solar cell.

Consider your potential kWh consumption.

What percentage of your present kWh consumption would you like solar power to offset? 50%, 70%, or 100%?

Multiply this percentage by your daily kWh consumption.

If you want your solar system to account for 70% of your kWh consumption, the estimator calculates it like this: 40 kWh per day x 0.70 = 28 kWh.

Determine how many solar boards required

A standard solar system produces about 1.24 kWh per day. Therefore, if you want to cover 100% of your daily kWh usage, you would require 30 solar boards (37 kWh daily consumption divided by 1.24 kWh per module).

Low-Interest Loans and Tax Credit are available

Typically, an 8.95 kW residential solar system will be eligible for Federal Tax Credit -26% off and the remainder is financed over 20 years. The resulting monthly solar payment is ~$119, and the electric bill savings are ~$130-150, creating immediate positive cash flow. Systems have a 25-year warranty on all major components.

What factors contribute to the solar panel system cost

When calculating solar power costs, there are several factors to acknowledge.

Equipment type

The two primary variables that affect solar costs are power density and color.

Power density is the amount of energy a solar board generates per unit of measure. The “denser” the panel, the costlier the price per watt.

Color is the other variable in solar systems.

A base panel has a blue cell, a white back, and a silver frame. Black frame modules have a black back sheet or black cell and are generally more expensive.

Roof type

Solar modules can be installed on metal, shingles, and flat roofs.

Roof shingles require a special fitting to fix the panel planks to the roof. With a grooved or seamed rooftop, you connect the planks directly to the metal. Or, mount the panels on a flat rooftop with a ballast holder.

Connection costs

Interconnection is the process of joining your solar power system to the area grid. Each local utility service provider has precise requirements for this.


The cost for solar energy panels also differs by area. You will find a cheaper cost per watt in warm regions and a higher price per watt in cold areas.

In either case, the prices of solar panels will eventually match. Warm states demand larger system sizes but cost less per watt, while cold places have a higher price per watt but smaller solar board sizes.

System size

The installation costs for solar power boards also depend on the size and capacity of your panel. A bigger solar board costs more. Installers typically require about 75 cents to $1.25 per watt for their services.

It's important to recognize that larger panels are an investment.. You may spend more out of pocket at first, but you will save on your electric expenses significantly in the long run.

Solar panel costs per watt

Systems come in a variety of sizes, varying from small 5W systems to 400W + premium products. Hence, the cost per watt rating helps you compare systems on an equal footing.

The cheapest cost-per-watt prospects give you total performance for every dollar spent but are also less space-efficient.

Federal tax credit

When you buy solar power systems, you qualify for a state solar tax credit. You will gain a portion of your solar board expenses back as reimbursement for investing in your own, clean energy. The rate you will get depends on when you buy your systems.

If you buy a solar panel between 2020 and 2022, you will obtain a tax reduction of 26 percent. In 2023, it will decrease to 22 percent. The homeowner loan will expire in 2024 but will continue at 10 percent for commercial developments.

With the federal tax credit, the earlier you start, the quicker the solar panel cost goes down! However, it is essential to understand that the brand you select will also affect overall profit. American solar partners offer a variety of solar module brands, so you can buy the systems you need at your preferred prices.

Federal Tax Credit is provided in the amount of 26% of the total solar system cost and is taken against the tax liability during the next tax filing. Those who don’t pay federal income taxes are generally unable to use the credit.
Installation and connection
Qualified American solar partners take care of everything from permits to installation. After you place your order, a qualified installer gathers remote aerial photos of your home, designs your system, takes care of any permits needed, and schedules your installation. An on-site verification will take place prior to the beginning of installation. After installation, a qualified installer schedules a city inspection and works with your utility company to commission the system.

Solar power map of the United States

In an effort to help residential and business owners determine the solar energy potential on their property and also determine the average cost for a solar board, energy and cost savings, and payback periods, the United States Department of Energy National Renewable Energy Laboratory (NERL) developed the Solar Power Map.

Solar Resource Maps and Data | Geospatial Data Science | NREL

The website prompts the user for their address, and the system retrieves information estimates on their property.

Once the user has verified the property data online, three types of systems can be analyzed: PV system, solar hot water heating system (SHW), or solar pool heating system (SPH).

These values can be used to determine the costs of solar power generation and ROI on solar boards.

To carry out your return calculation, split the total price of the solar board by the annual benefit of mounting the system.

While there are some upfront costs associated with going solar, solar electricity for home use is more popular due to its faster payback periods and tremendous savings.
