El análisis de cargas implica la recopilación de información sobre las cargas que servirá como base para el resto del proceso de diseño del sistema. Las clasificaciones de energía y las estimaciones de uso para las cargas necesarias y potenciales se reúnen en unas tablas: una para corriente continua y otra para corriente alterna. Es importante sobrestimar el uso para garantizar que el sistema tenga un tamaño adecuado. Si un sistema tiene diferencias extremas en el recursos solar o cargas durante el año, entonces puede ser necesario realizar una comparación de cargas y recurso solar del proceso de diseño detallado.
Al diseñar cualquier sistema, casi siempre es necesario explorar varios diseños diferentes con diferentes cargas y patrones de uso para llegar al mejor equilibrio entre costo y presupuesto.
Consideraciones adicionales:
- Si un sistema incluye un refrigerador, es necesario seguir el proceso de diseño detallado del sistema para tener en cuenta correctamente ciclos de trabajo.
- Se debe documentar la marca, el modelo y la potencia nominal de cualquier carga actualmente presente en el sitio. Las fotos son muy útiles.
- Si el diseño del sistema va a incorporar cargas que aún no se han comprado, se debe brindar orientación sobre el valor y la importancia de la compra de Cargas energéticamente eficientes.
- This process can be difficult in locations that do not currently have electricity or that have users that do not have experience with electricity beforehand. In these cases, there is a tendency to over-estimate and under-estimate appliance usage depending on the individual. The result is that more responsibility falls upon the person performing the load evaluation and the system designer to provide guidance and accurate estimates.
- Potential projects that do not currently have an electrical system will also require additional evaluation and design work to ensure that the building will have adequate outlets for (power receptacles) and lighting for the intended use of each room.

DC load evaluation
Typical direct current loads include lights, cell phones, and radios. If a system incorporates an inverter, it is important that its idle consumption is included in the DC load evaluation.
Step 1: Fill out DC load chart
| # | Load | Quantity | Watts | Total watts | Hours per day | Daily DC watt-hours |
|---|---|---|---|---|---|---|
| 1 | ||||||
| 2 | ||||||

- Load: The make and model or type of load.
- Quantity: The number of the particular load.
- Watts: The power rating in watts of the load.
- Total watts = Quantity × Watts
- Hours per day: The maximum number of hours the load(s) will be operated per day.
- Daily DC watt-hours = Total watts × Hours per day
Step 2: Determine DC energy demand
| Total daily DC watt-hours | = sum of Daily DC watt-hours for all loads |
|---|
AC load evaluation
The AC load evaluation is important for determining the total amount of energy that is required for the system, but also to properly size the inverter so that it has sufficient power to be able to feed the loads.
Step 1: Fill out AC load chart
| # | Load | Quantity | Watts | Total watts | Hours per day | Daily AC watt-hours |
|---|---|---|---|---|---|---|
| 1 | ||||||
| 2 | ||||||

- Load: The make and model or type of load.
- Quantity: The number of the particular load.
- Watts: The power rating in watts for the load.
- Total watts = Quantity × Watts
- Hours per day: The maximum number of hours the load(s) will be operated per day. If the load has a duty cycle 24 hours should be used.
- Days per week: The maximum number of days the load(s) will be operated per week.
- Daily AC watt-hours = Total watts × Duty cycle × Hours per day
Step 2: Deteremine AC energy demand
The total energy demand for all loads must be added up and then it must be multiplied by the average efficiency of the inverter to determine the actual total energy requirement. Inverter efficiency should be assumed to be .85 (85%). Some inverters will list higher peak efficiencies, but they will not achieve that level of efficiency under normal usage.
| Sum of daily AC watt-hours | = sum of Daily AC watt-hours for all loads |
|---|
| Total daily AC watt-hours | = sum of Daily AC watt-hours ÷ Inverter efficiency |
|---|
Step 3: Determine AC power requirement
| Total AC connected watts | = sum of Total watts |
|---|
Total daily energy demand
The total energy demand for the system is the added Daily DC-watt hours and Daily AC watt-hours for each time period.
| Daily watt-hours required | = Total daily DC watt-hours + Total daily AC watt-hours |
|---|
