Meaning, back of the napkin, PV is + - 77% efficient, minus "x" to pump the water to "x" elevation and the net result of the hydro = "____% efficient"</span><br style="color: rgb(0, 0, 0);"><br style="color: rgb(0, 0, 0);"><span style="color: rgb(0, 0, 0);">It would be using the reservoir as the battery.</span><br
style="color: rgb(0, 0, 0);"><br style="color: rgb(0, 0, 0);"><span style="color: rgb(0, 0, 0);">There is approximately 300' of elevation from the PV system and water source to the reservoir area.</span><br style="color: rgb(0, 0, 0);"><br style="color: rgb(0, 0, 0);"><span style="color: rgb(0, 0, 0);">I recall about 15 years ago, I visited a member on this lists Vermont home and he had a pond at the top of his property, but i don't recall how the source got to the reservoir?

on their grid. We are seeing this happen here now and I was wondering if any of you have encountered this or are anticipating this in your areas?</span><br><br style="color: rgb(0, 0, 0);"><span style="color: rgb(0, 0, 0);">Any suggestions, calcs, recommendations, feedback would be appreciated.</span> <br style="color: rgb(0, 0, 0);"><br style="color: rgb(0, 0, 0);"><span style="color: rgb(0, 0, 0);">Keith</span><br></div></div></body></html>
