Solar Home system



A small solar electric or photovoltaic (PV) system can be a reliable and pollution-free producer of electricity for your home or office. Small PV systems also provide a cost-effective power supply in locations where it is expensive or impossible to send electricity through conventional power lines, even for use in emergencies.

Because of their modularity, PV systems can be designed to meet any electrical requirement, no matter how large or how small. A stand-alone home solar electric or PV system operates "off-grid" it isn't connected to a electricity distribution grid operated by a utility.

Accurately sizing the components of your solar electric or PV system helps ensure that your system will produce the amount of power you want it to produce. This is especially important for stand-alone systems, which are not connected to the electricity grid. Because PV is modular, you can always add to your solar energy collector should you need more power down the road.

Below I introduce the technical description of my "Solar Home system" that I have build in the apartment, for the generation and accumulation of electrical energy exclusively for computer use, internet and lighting, in case of emergency in order to keep working.

Tips para mis amigos en Venezuela:


A.- El tipo de Panel Solar ideal es el fotovoltáico "Monocristalino" (celda hexagonal megra) que es el más eficiente. Los tipo "Policristalino" (azules), "Amorfos", "Arseniuro", "Teluro", "Diseleniuro" o "Tándem" no son tan eficientes (hasta la fecha).

B.- Lo más barato es construir uno mismo el panel solar, comprando solo las fotoceldas y armarlo!!! https://youtu.be/7urmHuOTp8k

C.- Para alimentar una nevera necesitas que tu inversor sea de 1.000 watios mínimo. Lo ideal es calcular primero la carga exacta (no todas consumen igual), para eso hay un aparatico llamado "Vatímetro" (Power meter).

D.- Para alimentar aparatos electrónicos, el tipo de inversor a utilizar debe ser "Puse Sine Wave" (Onda Sinusoidal Pura), ya que la electricidad debe ser uniforme. Los del tipo "Modified Sine Wave" (Onda Sinusoidal Modificada) son para cargas especiales y motores.

E.- todos los enlaces que he puesto con referencia a equipos en Amazon.com se consiguen más baratos en eBay.com comprando directamente al mayorista en China.

F.- Lo más difícil de conseguir puede ser la batería, ya que por su peso no es conveniente importar por courrier. En Mercadolibre.com.ve todavía se consiguen todos los componentes a buen precio.

G.- El tipo de baterías que se debe utilizar para sistemas fotovoltaicos son las tipo "descarga profunda" cuyo suministro eléctrico es uniforme. Las baterías para vehículos no son aptas por estar diseñadas para enviar la mayor carga eléctrica para el arranque (encender).

H.- Las baterías deben almacenarse sobre una tabla de madera preferiblemente (si le colocas ruedas mejor), ya que se descargan si las colocan directamente al suelo.
