A Solid Structurally Sound Roof
Solar panels arent extremely heavy for their size, but they do weigh a good amount. For that reason, youll need to make sure that your roof is in good shape, that it doesnt need to be replaced anytime soon, and that it can handle the extra weight.
If you are in need of a new roof, then you can knock out two birds with one stone by replacing it when you decide to also install solar.
Youll also be able to regain some of the cost that comes with installing a new roof through the local, state, and federal incentives if you get it installed before those incentives go away. Any of our solar consultants will be able to help you work out whether or not you should get your roof replaced before going solar. Be sure to mention it right away if youre concerned about needing it replaced.
Calculate Power Per Building

This Map Shows The Yearly Average For An Average January Day But With A Solar Tracking Mount
Compare this to the previous map, and you can see what a difference a tracking mount system can make. The example shown is for 2-axis tracker, like the WattSun. A single axis tracker, like the Zomeworks, will be a little less, but still considerably more than a fixed array. The biggest problem with tracking mounts is that they give the biggest increase in the summer, while the biggest need for power is in the winter. If you have plenty of power in the summer, but fall short in winter, your best option may be to use a maximum power point tracker . Tracking mounts used to make a lot more sense when solar panels were selling in the $10+ a watt range, but with current prices around the $4.50 to $5.50 per watt range, the economic advantages of tracking are less.
First Solar Site Check Find True South
Before you hire a site assessor, there are some basics you can check yourself. A good site for a PV array in the northern hemisphere has a location that is within 10° of true south. Remember that true south can be widely different than magnetic south. The US Geological Survey has a map showing the declination lines. Along the Mississippi River, True North and Magnetic North are close enough to ignore. In California, they are from 12° to 17° off.

How Much Is Your Energy Bill
Knowing how much you pay for energy is the first step in evaluating whether your house is a good candidate for solar. The main question is, will it save you money? In some areas, electricity is very inexpensive. For most homeowners, the electricity bill is a dreaded monthly expense. The general rule is that solar makes the most financial sense for someone with a monthly electricity bill of at least $75. Why? Because going solar replaces utility energy with solar energy, and we want our customers to see a return on that investment by paying less for that energy. A utility bill of $75 is the threshold at which residential solar customers will see solar savings. There are several ways to go solar, depending on a customers needs and goals. SunPower offers zero-down lease, loan and cash purchase options each with different benefits. Ask your local solar expert about local and federal incentives and electricity policies where you live.
The overall idea is to pay less than you currently pay, lock in your electricity rate and save money by generating your own clean energy onsite.

Home And Roof Regulations
If your home is a condo or townhouse governed by a homeowners association , you may not actually have the final say about what goes on your roof. Many HOAs regulate the outer structure of neighborhood homesincluding the roofs. So before you sign any contracts, find out what the HOA regulations are for solar panel installation.
Likewise, if youre a renter, you may not be able to make the decision to go solar on your ownits ultimately the landlords call. However, its worth contacting your neighbors to see if theyre also interested in solar power. If several tenants would like to install solar panels, you may be able to make a proposal to the landlord for approval to go ahead.
Aggregate Cells By Building
First, for every building, you’ll calculate the area covered by its suitable cells and their average solar radiation . You’ll do that using the Zonal Statistics as Table tool.
The Zonal Statistics as Table tool will look within each building footprint polygon and aggregate the suitable cells it contains.
The Building_ID field is a unique identifier for each building footprint. Using this field as the zone field will ensure that each building footprint is clearly identified.
You can choose to calculate several types of statistics. You’ll calculate the Mean to determine the average solar radiation per square meter for each building.
The tool runs and the new table is added to the bottom of the Contents pane, under Standalone Tables.

Degeneration Prospective Of Sunpower Panels
Shoppers of SunPower doors can easily access product and producers guarantees within 25 40 years. What is actually the offer concerning SunPowers degradation ability per annum?Solar Potential By Address
All solar powers shed their potential to fetch and transmit sun rays for storage as they grow older. SunPower asserts their array of solar panels will simply weaken regarding 0.2% every 12 months.
At such a price, users can easily expect around 92% capacity coming from their solar energy panels throughout operations. Continual use these solar panels could lower the max anticipated capability to concerning 86%.
How Much Cloud Coverage Does Your Home Have
Beyondthe immediate vicinity of your house, there is another commonobstruction that creates shade and limits solar potential: CloudCoverage.
Clouds limit the amount of power that a solar panel can produce.
Solar panels only generate between 10-25% of potential solar power on days when it is cloudy.
Areas with lower cloud coverage are best for solar, areas that experience high levels of cloud coverage or fog have less chance to produce solar energy in the most efficient way.
However, even in the cloudiest cities in the United States like Seattle, Washington, roofs can be suitable for solar panels.
It all depends on the amount of electricity that you need.
Cities like Las Vegas, Nevada make it easy to choose solar for your roof.
With an average of 294 sunny days each year, the chance that a house is suitable for solar panels is very high in Las Vegas, as more sunlight means more hours of the day in which solar energy can be generated, used, or stored.
All in all, an obvious but important factor to know if your house is a good candidate for solar panels is simple: less clouds are better for solar energy.

Utilize Solar Panel Trackers
If your budget allows, consider solar panel tracking systems. They can improve a systems output by ensuring constant, direct exposure to the sun, both during the day and across seasons. Axis trackers generate more electricity by using about the same amount of space as fixed systems.
However, its important to note that solar trackers are expensive. While a standard 4 kW fixed solar panel system costs about $11,400 after incentives, a single-axis tracking system that can produce the same amount of power such as the Smartflower is $20,000, or almost double that.

A Focus On Solar Savings
Both the Google and UNSW platforms highlight the economic benefits of solar PV installation. Sunroof includes a personalised solar savings estimator that can tell each household just how much it could save on electricity per year by installing solar panels.
Solar is expected to be the least-cost form of generation technology in future and rooftop PV is already an excellent investment for households, giving typical paybacks of four to six years, says Bruce. The Australian energy market operator expects that rooftop PV, which is at about 6GW now, will be around 20GW by 2030.
As SunSPoT is developed and refined, it will place a higher emphasis on the economics of solar PV installation, working with innovative energy data companies Solar Analytics and Enosi.
The new version of SunSPoT that we have under development will give an estimate of the bill savings from rooftop solar and battery storage, says Bruce. Because solar PV generates at certain times of the day and energy is worth different amounts depending on the tariff, it is difficult for consumers to determine the value of demand-side investments and for planners and decision makers to identify the best opportunities for these technologies.

Do They Have To Be Attached To The Roof
The majority of solar panels owners choose to have their panels attached to their roof. This has led to something of an assumption that they have to be placed on the roof. But this is not necessarily the case. Roof-mounted solar panels do have plenty of advantages such as being out of the shade of trees, as well as being protected from heavy wind.
However, free-standing solar panels can also be valuable as they can be placed facing south and at any angle you wish.

Create A Hillshade Effect
Although patterns in the DSM suggest the locations of buildings and vegetation, you can better visualize the surface by creating a hillshade effect. A hillshade raster layer uses a realistic shading effect to depict elevation.
The Raster Functions pane appears.
Note:
Raster functions are tools that apply calculations directly to a raster’s pixel values without requiring new data to be saved. As such, they are very efficient.
The Hillshade tool opens.
A new layer, named Hillshade_DSM, is added to the map. For optimum visual effect, youll combine hillshade and DSM layer symbolization.
The DSM layer is set to 40 percent layer transparency. When it is drawn above the hillshade, both layers are visible.
Note:
The hillshade layer that you created with a raster function is computed dynamically and not written on disk. So, if you remove it from the Contents pane, it will completely disappear, and youll have to recreate it.

Create A Solar Radiation Layer
To create the solar radiation layer, youll use the Area Solar Radiation tool. This tool is part of the ArcGIS Spatial Analyst extension and takes a DSM as input. It calculates radiation based on a sophisticated model that takes into account the position of the sun throughout the year and at different times of day, obstacles that may block sunlight such as nearby trees or buildings, and the slope and orientation of the surface. You can read more about modeling solar radiation in the Modeling solar radiation help documentation.
The DSM provides the necessary information on obstacles, orientation, and slope. The output will be a raster layer where each cell value is the amount of solar radiation in watt-hours per square meter at that location.
Note:
The Area Solar Radiation tool is computationally intense and can take between 20 and 90 minutes to run. For the purposes of this exercise, you will have the option of running the tool yourself or using a solar radiation raster layer that has already been created and was provided with the project data. Regardless of your choice, youll first learn how to select the right parameter values for the tool.
