Yes, you can successfully install solar panels on the flat roof of your home or business. However, there are some challenges to be aware of. Flat roofs have a minimal slope allowance that will accommodate solar PV panel systems. A roof having a rise of 0.25 inches over a 12-inch run — known as a 0.25:12 pitch roof — is considered a flat roof.
Not only are flat roofs a viable solar electricity producing surface, but the cost can be on par with that of standard sloped roof installation. Use this solar calculator to get a ballpark of how much solar would cost for you home and how much you can save by going solar.

Khartoum is located at a latitude of 15. Here is the most efficient tilt for photovoltaic panels in Khartoum: Your photovoltaic panels need to be angled facing south.
This study provides estimates of photovoltaic (PV) panel optimal tilt angles for all countries worldwide. It then estimates the incident solar radiation normal to either tracked or optimally tilted panels relative to horizontal panels globally. Optimal tilts are derived from the National Renewable Energy Laboratory's PVWatts program.
Table 1. Optimal tilt angles for fixed tilt solar PV panels for all countries of the world. Indicates the optimal tilt angle is between +/−10°, thus panels will likely be tilted in practice either +10° for positive values or −10° for negative values to allow for rain to naturally wash them. Data are derived from PVWatts (NREL, 2017).
A critical parameter for installing fixed-tilt panels is the tilt angle, since PV panel output increases with increasing exposure to direct sunlight. Energy modelers also need to know the optimal tilt angle of a panel for calculating regional or global PV output in a given location or worldwide.
Our solar panel angle calculator takes the guesswork out of panel positioning, suggesting panel tilt angles based on your location's latitude and your willingness to reposition based on the sun's seasonal dance across the sky. Start by entering your location in the search box.
Panel altitude, latitude, longitude, and angle relative to the sun are used to estimate exposure of the panel to sunlight. Air temperature and wind speed data are used to estimate panel temperature. Here, PVWatts is used to estimate annually averaged solar output in all countries of the world assuming tilted panels.
In sum, for optimal utility PV output, 1-axis horizontal tracking is recommended, except for the highest latitudes, where optimal tilting is sufficient. However, decisions about panel configuration also require knowing tracking equipment and land costs, which are not evaluated here.

Here's how to calculate the power output of your solar array, regardless of how you're wiring your panels together -- and regardless of. Here's a quick overview of how to wire solar panels in series and parallel. For more in-depth instructions, check out our full tutorial. Full.
A solar panel (formally known as PV module) is an optoelectronic device made from multiple solar cells normally wired in series. Here in Italy the best selling panel is the 230Wp 32V panel, that is composed of 60 polycrystalline solar cells wired in series.
So, if you connect two solar panels with a rated voltage of 40 volts and a rated amperage of 5 amps in series, the voltage of the series would be 80 volts, while the amperage would remain at 5 amps. Putting panels in series makes it so the voltage of the array increases.
The lower the threshold voltage, the lower the dissipation of solar power on the diode. If we have two or more solar panels with the same voltage but with different current, it is NOT possible to wire them in series. Nonetheless it is possible to wire them in parallel.
Series connection is the most popular configuration for home grid-tie systems: cheap and offers good efficiency. When you connect solar panels in series, their voltages add up. The current is as low as a single panel in an array provides. Maximum power point technology in an inverter allows it to convert extra voltage to current.
If you decide to apply a mixed connection, it's practical your solar array to comprise an even number of panels (a multiple of 2), for example, 4 panels (2 in series and 2 in parallel) or 6 panels (3 in series and 2 in parallel).
The other system components, such as a charge controller, battery, and inverter. There are two main types of connecting solar panels – in series or in parallel. You connect solar panels in series when you want to get a higher voltage. If you, however, need to get higher current, you should connect your panels in parallel.
