The collection box: This device is used to collect all the power from the various photovoltaic arrays. The panels are wired up, in series, to create several groups or arrays. each array puts out about 600 volts DC. The connection box feeds the wires through attic to the inverters.
This system has two inverters due the number of PV panels and the desired expansions options. The inverter take the DC power created by the photovoltaic panels and covert it in to 240v AC power. These inverters are a little more sophisticated then the inverters you use in you car to get 110 power. These are full sign-wave inverters. A fail-safe system is built into the inverters to shut down if the street service is interrupted. The interruption is to protect any power Company employee that is working to restoring the main grid.
Two inverter introduces a problem as both inverter takes up two slots in the electrical panel. I was lucky and had the space in the panel. We had upgraded to a 200amp panel two years earlier in preparation and anticipation of adding solar.
There are also some advantages to having to inverters. If one inverter fails you do not loose all your power production abilities. Half of you system will still be producing usable power. The other advantage is the cost less to replace if one fails.
Next the photovoltaic panels.
An idea whose time has come!
For too long we have been too complacent about the workings of Congress. Many citizens had no idea that members of Congress could retire with the same pay after only one term, that they specifically exempted themselves from many of the laws they have passed (such as being exempt from any fear of prosecution for sexual harassment) while ordinary citizens must live under those laws. The latest was to exempt themselves from the Healthcare Reform … in all of its forms. Somehow, that doesn’t seem logical. We do not have an elite that is above the law.
I truly don’t care if they are Democrat, Republican, Independent or whatever. The self-serving must stop.
It is also time to stop the practice of sneaking unpopular legislation through, piggybacked on legislation which is more likely to pass by including a single purpose rule. Many State constitutions already have such a rule that is designed to avoid complexity in laws and to avoid any hidden consequences that legislators or voters may miss when reading the proposed law.
The 26th amendment (granting the right to vote for 18 year-olds) took only 3 months & 8 days to be ratified! Why? Simple! The people demanded it. That was in 1971…before computers, before e-mail, before cell phones, etc.
Of the 27 amendments to the Constitution, seven (7) took 1 year or less to become the law of the land…all because of public pressure.
I’m asking each addressee to forward this Email to a minimum of twenty people on their Address list; in turn ask each of those to do likewise.
In three days, most people in The United States of America will have the message. This is one proposal that really should be passed around.
Proposed 28th Amendment to the United States Constitution:
“Congress shall make no law that applies to the citizens of the United States that does not apply equally to the Senators and/or Representatives; and, Congress shall make no law that applies to the Senators and/or Representatives that does not apply equally to the citizens of the United States . Nor shall Congress enact any legislation that shall embrace more than one subject, which subject shall be clearly expressed in its title”
