Sure, I'd be more than happy to provide my input on this. First, let’s consider 5 tips that an applicant might benefit from when preparing their application:

1. Adapt to the Job Description: In my experience, a common mistake committed by most applicants is to treat their CVs and cover letters as fixed documents, only changing the recipient’s name and address. For this job, tailor your CV to emphasize your experience or knowledge with solar and electrical products and sales.

2. Highlight Your Tasks and Successes in Previous Sales Roles: This job requires the ability to generate leads and convert them into paying customers. Detail your past experiences, focusing on how you met sales targets, how you carried out product demos, and your customer service skills.

3. Demonstrate Technical Knowledge: The employer is looking for someone who can provide technical information about solar-related equipment. If you have any relevant qualifications or experience, be sure to place this prominently in your CV or cover letter.

4. Communicate Your Ability to Meet Customers' Needs: This job requires an understanding of customers' specific requirements towards a solar system and budget. Highlight any experiences where you had to match products or services to the specific needs of customers.

5. Show Proactivity in Learning and Engagement: Showcase any additional courses or certifications related to solar and electrical systems, as well as instances where you've liaised with potential customers proactively to increase sales.

Now, let's focus on 5 areas of the job listing that applicants must take significant note of:

1. How To Apply: The application process is straightforward with the submission of a cover letter and CV to a specific email. Do not overlook this or attempt to submit the application in any other way.

2. Experience Required: At least 1-year of sales and marketing experience is required, along with either a certificate or diploma. If you don’t meet the criteria, addressing this in your cover letter with valid reasons and transferable skills can prove beneficial.

3. Salary Structure: The salary offers a fixed $200 along with commission. Ensure you understand the implications of a commission-based compensation structure and whether that suits your work style.

4. Knowledge and Expertise: Extensive familiarity with solar and electrical products is paramount for this role. Understand the importance of this requirement and be prepared to demonstrate your knowledge in your application and potential interview.

5. Key Job Duties and Roles: Pay particular attention to the responsibilities of the role. These will give you insight into day-to-day interactions and your core responsibilities.

Next, let me highlight top 3 elements that can make a candidate stand out:

1. Certifications in Solar Systems: What I have noticed over time is that additional certifications, especially in niche products like solar systems, paint you as a proactive learner willing to invest in your knowledge.

2. Relevant, Successful Sales Stories: In my experience, concrete examples of your success in a related sales post illustrating how you achieved or exceeded sales targets will make you stand out.

3. Efficient Problem-Solving Skills: Drawing attention to situations where you've diagnosed site suitability, calculated potential solar array production, or delivered successful customized energy management packages effectively can be a differentiator.

Lastly, let’s emphasize 3 important things often overlooked by novice applicants:

1. The Importance of Cover Letter: Job seekers often underestimate the power of a well-crafted cover letter. The employer has specifically asked for it, indicating that they do consider it a key part of the application.

2. Subtle Indications of Autonomy and Initiative: This job expects the sales representative to generate his/her own leads, develop accounts, create sales plans. This indicates the company appreciates autonomy and initiative.

3. Commission-Based Role: A significant part of the compensation for this role could be commission-based. Candidates should consider if the risk-reward nature of such a compensation package aligns with their personal working style and financial needs.

Remember, attention to detail can make the difference between an application that gets overlooked and one that lands an interview. All the best!
