solar cell orientation
It is obvious that solar panels produce more energy when pointed directly at the sun. Therefore, any facility should provide maximum light solar surface. Ideally, even in winter, they should receive full sun from about 9am to 3pm. Surprisingly, there is still a wide range of elevations and orientation that will give a useful result. If your facility placement is limited, passive monitoring can be treated or even reflectors to increase the light falling on they. If you are considering a DIY solar project, it is necessary to study carefully how to orient the panels.
A major concern is the development of the right inclination to differences in latitude and season. If possible, the adjustable brackets are preferable to maximize efficiency. A very good approximation for the angle of inclination of season, latitude minus 15 ° in the summer, latitude 15 ° in winter, and establish height panels in spring / autumn. This ensures that the panels are angled to get the most out of direct light. Note that most Roof slope angles allow acceptable panel toward the sun and still provide a good average output power over the year, but you are advised to verify this.
The amount of energy that the panels turn is directly proportional to the received power of the sun and will vary during the day and varies throughout the year may vary according to the hours of sunshine per month. It varies not only during the day, but as the seasons progress, solar energy systems are rated as a means of energy output peak Sun solar energy available is equal to the daily solar radiation (kWh per square meter), and since this varies usually given as a monthly average.
Solar energy systems are not only affected by the quality of sunlight throughout the day, any shade also affect their production. Trees, buildings and elevated structures that cast shadows can affect part of a settlement. Not that not only the cells not work as efficiently, but the surrounding cells are affected by this (which is effectively the resistance in the circuit) and the cells may overheat, reducing their effectiveness. Even high hills on the horizon may limit the "hours of sun in early morning or late afternoon.
Another problem may be that if a group or parent not protected by a lock or bypass diode, when a group fails to produce energy, either because of the shadow, clouds or night, current can flow Leak and their batteries.
Do not forget that the panels or the distance matrix is the storage controller or should be taken into account. long cables can be affected by simple resistance wire and no loss of power between the array and batteries. One solution is to connect the panels in a series to provide a higher voltage (but low amperage), then you will have to balance out the battery stack.
